74LVC1G3157GX中文资料安世数据手册PDF规格书

1. General description

The 74LVC1G3157 is a single-pole double-throw analog switch with a digital select input (S), two

independent inputs/outputs (Y0 and Y1) and a common input/output (Z). Control inputs can be

driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators

in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at control inputs makes the circuit tolerant of slower input rise and fall times.

2. Features and benefits
