74HC2G66-Q100; 74HCT2G66-Q100
Dual single-pole single-throw analog switch
Rev. 2 — 6 November 2018
Product data sheet
1. General description
The 74HC2G66-Q100; 74HCT2G66-Q100 is a dual single pole, single-throw analog switch. Each switch has two input/output terminals (nY and nZ) and a digital enable input (nE). When nE is LOW, the analog switch is turned off. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits

[1] To avoid drawing VCC current out of pin nZ, when switch current flows in pin nY, the voltage drop across the bidirectional switch must not exceed 0.4 V. If the switch current flows into pin nZ, no VCC current will flow out of terminal nY. In this case there is no limit for the voltage drop across the switch, but the voltage at pins nY and nZ may not exceed VCC or GND.
