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.
