Overview
The 74LVC1G157GW-Q100H is a single 2-input multiplexer manufactured by Nexperia USA Inc. This device is designed to select data from two data inputs (I0 and I1) under the control of a common data select input (S). It is particularly useful in mixed 3.3 V and 5 V environments, allowing it to act as a translator between these voltage levels. The multiplexer is fully specified for partial power-down applications and features high noise immunity, CMOS low power dissipation, and direct interface with TTL levels.
