8 Detailed Description

8.1 Overview

This single analog switch is designed for 1.65-V to 5.5-V VCC operation in automotive applications.

The SN74LVC1G66-Q1 device supports analog and digital signals. The device permits bidirectional transmission of signals with amplitudes of up to 5.5 V (peak). Like all analog switches, the SN74LVC1G66-Q1 is bidirectional.

8.3 Feature Description

This device is tested for operation in automotive applications. The SN74LVC1G66-Q1 has a wide VCC range, allowing rail-to-rail operation of signals anywhere from a 1.8-V system to a 5-V system. In addition, the control input (C Pin) is 5.5-V tolerant, allowing higher-voltage logic to interface to the switch control system.
