+5V Powered RS-232

Features

Transmitters/Receivers

• Meets All RS-232E and V.28 Speciﬁcations

The HIN230-HIN241 family of RS-232 transmitters/receivers

interface circuits meet all ElA RS-232E and V.28 specifications,

and are particularly suited for those applications where ±12V is

not available. They require a single +5V power supply (except

HIN231 and HIN239) and feature onboard charge pump

voltage converters which generate +10V and -10V supplies

from the 5V supply. The HIN233 and HIN235 require no

external capacitors and are ideally suited for applications where

circuit board space is critical. The family of devices offer a wide

variety of RS-232 transmitter/receiver combinations to

• Requires Only Single +5V Power Supply

- (+5V and +12V - HIN231 and HIN239)

• High Data Rate. . . . . . . . . . . . . . . . . . . . . . . . . . . 120kbps

• HIN233 and HIN235 Require No External Capacitors

• Onboard Voltage Doubler/Inverter

• Low Power Consumption

• Low Power Shutdown Function

accommodate various applications (see Selection Table).

• Three-State TTL/CMOS Receiver Outputs

• Multiple Drivers

The drivers feature true TTL/CMOS input compatibility, slew-

rate-limited output, and 300Ω power-off source impedance.

The receivers can handle up to ±30V, and have a 3kΩ to 7kΩ

input impedance. The receivers also feature hysteresis to

greatly improve noise rejection.

- ±10V Output Swing for 5V lnput

- 300Ω Power-Off Source Impedance

- Output Current Limiting

- TTL/CMOS Compatible

- 30V/µs Maximum Slew Rate

• Multiple Receivers

- ±30V Input Voltage Range

- 3kΩ to 7kΩ Input Impedance

- 0.5V Hysteresis to Improve Noise Rejection

Applications

• Any System Requiring RS-232 Communication Ports

- Computer - Portable, Mainframe, Laptop

- Peripheral - Printers and Terminals

- Instrumentation

- Modems

SHUTDOWN

NC

Enable input. This is an active low input which enables the receiver outputs. With EN = 5V, the outputs are placed in a high

impedance state.

Shutdown Input. With SHUTDOWN = 5V, the charge pump is disabled, the receiver outputs are in a high impedance state

and the transmitters are shut off.

No Connect. No connections are made to these leads.

Detailed Description

The HIN230 thru HIN241 family of RS-232

transmitters/receivers are powered by a single +5V power

supply (except HIN231 and HIN239), feature low power

consumption, and meet all ElA RS-232C and V.28

specifications. The circuit is divided into three sections: The

charge pump, transmitter, and receiver.

= 4.5V, and maximum allowable operating

temperature. The transmitters have an internally limited output

slew rate which is less than 30V/µs. The outputs are short

circuit protected and can be shorted to ground indefinitely. The

powered down output impedance is a minimum of 300Ω with

Charge Pump

±2V applied to the outputs and V

= 0V.

An equivalent circuit of the charge pump is illustrated in Figure

1. The charge pump contains two sections: the voltage

doubler and the voltage inverter. Each section is driven by a

two phase, internally generated clock to generate +10V and -

10V. The nominal clock frequency is 16kHz. During phase one

with respect to ground to produce a signal across C4 equal to

-2V . The charge pump accepts input voltages up to 5.5V.

CC

Receivers

The output impedance of the voltage doubler section (V+) is

approximately 200Ω, and the output impedance of the voltage

inverter section (V-) is approximately 450Ω. A typical

application uses 1µF capacitors for C1-C4, however, the value

is not critical. Increasing the values of C1 and C2 will lower the

output impedance of the voltage doubler and inverter,

increasing the values of the reservoir capacitors, C3 and C4,

lowers the ripple on the V+ and V- supplies.

The receiver inputs accept up to ±30V while presenting the

required 3kΩ to 7kΩ input impedance even if the power is off

(V

= 0V). The receivers have a typical input threshold of

CC

1.3V which is within the ±3V limits, known as the transition

region, of the RS-232 speciﬁcations. The receiver output is

0V to V . The output will be low whenever the input is

CC

greater than 2.4V and high whenever the input is ﬂoating or

driven between +0.8V and -30V. The receivers feature 0.5V

hysteresis to improve noise rejection. The receiver Enable

line EN, when set to logic “1”, (HIN235, 236, 239, 240, and

241) disables the receiver outputs, placing them in the high

impedance mode. The receiver outputs are also placed in

the high impedance state when in shutdown mode.

During shutdown mode (HIN230, 235, 236, 240 and 241),

SHUTDOWN control line set to logic “1”, the charge pump is

turned off, V+ is pulled down to V , V- is pulled up to GND,

CC

and the supply current is reduced to less than 10µA. The

transmitter outputs are disabled and the receiver outputs are

placed in the high impedance state.

where ±12V power supplies are not available for

In applications requiring four RS-232 inputs and outputs

(Figure 10), note that each circuit requires two charge pump

capacitors (C1 and C2) but can share common reservoir

capacitors (C3 and C4). The beneﬁt of sharing common

reservoir capacitors is the elimination of two capacitors and

the reduction of the charge pump source impedance which

effectively increases the output swing of the transmitters.
