NC7WB66

TinyLogic Low Voltage UHS Dual SPST

Normally Open Bus Switch

General Description

Features

■ Useful in both analog and digital applications

■ Space saving US8 surface mount package

■ MicroPak leadless package

The NC7WB66 is an ultra high-speed (UHS) dual single-

pole/single-throw (SPST) bus switch. The device is fabri-

cated with advanced sub-micron CMOS technology to

achieve high speed enable and disable times and low On

Resistance over a broad V_CCrange. The device is speci-

■ Typical 7Ω On Resistance @ 5V V_CC

■ Broad V_CCoperating range: 1.65V to 5.5V

fied to operate over the 1.65 to 5.5V V_CCoperating range.

The device is organized as a dual switch with independent

CMOS compatible switch enable (OE) controls. When OE

is HIGH, the switch is ON and Port A is connected to Port

B. When OE is LOW, the switch is OPEN and a high-

impedance state exists between the two ports. The enable

inputs tolerate voltages up to 5.5V independent of the V_CC

■ Rail-to-rail signal handling

■ Power down high impedance control inputs

■ Control inputs are overvoltage tolerant

■ Control inputs are CMOS compatible

operating range.

Note 1: The “Absolute Maximum Ratings” are those values beyond which

the safety of the device cannot be guaranteed. The device should not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the absolute maximum ratings.

The “Recommended Operating Conditions” table will define the conditions

for actual device operation.

Note 2: The input and output negative voltage ratings may be exceeded if

the input and output diode current ratings are observed.

Note 3: Unused inputs must be held HIGH or LOW. They may not float.
