GENERAL DESCRIPTION

SHDN

GND

The ADM222, ADM232A, ADM242 are a family of high-speed

RS-232 line drivers/receivers offering transmission rates up to

200 kB/s. Operating from a single 5 V power supply, a highly

efficient on-chip charge pump using small (0.1 µF) external

capacitors allows RS-232 bipolar levels to be developed. Two

RS-232 drivers and two RS-232 receivers are provided on

each device.

functions are disabled. The ADM222 is available in 18-lead

DIP and in a wide surface-mount (SOIC) package.

The devices are fabricated on BiCMOS, an advanced mixed

technology process that combines low power CMOS with high-

speed bipolar circuitry. This allows for transmission rates up to

200 kB/s, yet minimizes the quiescent power supply current to

under 5 mA.

The ADM242 combines both shutdown (SHDN) and enable

(EN) functions. The shutdown function reduces the supply

current to 0.1 mA. During shutdown, the transmitters are dis-

abled but the receivers continue to operate normally. The

enable function allows the receiver outputs to be disabled

thereby facilitating sharing a common bus. The ADM242 is

available in 18-lead DIP and in a wide surface-mount (SOIC)

package.

The ADM232A is a pin-compatible, high-speed upgrade for the

AD232 and for the ADM232L. It is available in 16-lead DIP

and in both narrow and wide surface-mount (SOIC) packages.

The ADM222 contains an additional shutdown (SHDN) func-

tion that may be used to disable the device, thereby reducing the

supply current to 0.1 µA. During shutdown, all transmit/receive

ADM222/ADM232A/ADM242

GENERAL INFORMATION

The ADM222/ADM232A/ADM242 are high-speed RS-232

drivers/receivers requiring a single digital 5 V supply. The RS-232

standard requires transmitters that will deliver 5 V minimum

on the transmission channel and receivers that can accept signal

levels down to 3 V. The parts achieve this by integrating step-

up voltage converters and level-shifting transmitters and receivers

onto the same chip. CMOS technology is used to keep the

power dissipation to an absolute minimum. All devices con-

tain an internal charge pump voltage doubler and a voltage

inverter that generates 10 V from the 5 V input. Four exter-

nal 0.1 µF capacitors are required for the internal charge pump

voltage converter.

V_CC= 5 V, the switching threshold is 1.25 V typical. Unused

inputs may be left unconnected, as an internal 400 kΩ pull-up

resistor pulls them high forcing the outputs into a low state.

As required by the RS-232 standard, the slew rate is limited to

less than 30 V/µs without the need for an external slew limiting

capacitor, and the output impedance in the power-off state is

greater than 300 Ω.

Receiver Section

The receivers are inverting level-shifters that accept RS-232

input levels ( 3 V to 15 V) and translate them into 5 V TTL/

CMOS levels. The inputs have internal 5 kΩ pull-down resistors

to ground and are also protected against overvoltages of up to

30 V. The guaranteed switching thresholds are 0.8 V mini-

mum and 2.4 V maximum, which are well within the 3 V

RS-232 requirement. The low level threshold is deliberately

positive as it ensures that an unconnected input will be inter-

preted as a low level.

The ADM222/ADM232A/ADM242 is a modification, enhance-

ment and improvement to the AD230-AD241 family and

derivatives thereof. It is essentially plug-in-compatible and does

not have materially different applications.

CIRCUIT DESCRIPTION

The internal circuitry consists of four main sections. These are:

The receivers have Schmitt trigger input with a hysteresis level

of 0.5 V. This ensures error-free reception for both noisy inputs

and for inputs with slow transition times

Charge Pump Voltage Converter

TTL/CMOS to RS-232 Transmitters

RS-232 to TTL/CMOS Receivers

Enable and Shutdown Functions.

Enable and Shutdown Functions

On the ADM222, both receivers are fully disabled during

shutdown.

Charge Pump DC-DC Voltage Converter

The Charge Pump Voltage converter consists of an oscillator

and a switching matrix. The converter generates a 10 V supply

from the input 5 V level. This is done in two stages using a

switched capacitor technique. The 5 V input supply is doubled

to 10 V using capacitor C1 as the charge storage element. The

–10 V level is also generated from the input 5 V supply using C1

and C2 as the storage elements.

On the ADM242, both receivers continue to operate normally.

This function is useful for monitoring activity so that when it

occurs, the device can be taken out of the shutdown mode.

The ADM242 also contains a receiver enable function (EN)

which can be used to fully disable the receivers, independent

of SHDN.

Capacitors C3 and C4 are used to reduce the output ripple.

Their values are not critical and can be reduced if higher levels

of ripple are acceptable. The charge pump capacitors C1 and

C2 may also be reduced at the expense of higher output imped-

ance on the V+ and V– supplies.

APPLICATIONS INFORMATION

A selection of typical operating circuits is shown in TPCs 1–6

and Figure 13.

2.0V

The V+ and V– supplies may also be used to power external

circuitry if the current requirements are small. Please refer to

the typical performance characteristics which shows the V+, V–

output voltage vs. current.

100

In the shutdown mode the charge pump is disabled and V+

decays to V_CCwhile V– decays to 0 V.

Transmitter (Driver) Section

The Drivers convert TTL/CMOS input levels into RS-232

output levels. With V_CC= 5 V and driving a typical RS-232

load, the output voltage swing is 9 V. Even under worst-case

conditions the drivers are guaranteed to meet the 5 V RS-232

minimum requirement.
