1. General description

The 74LVC2G53 is a single-pole double-throw analog switch with a digital select input (S), two

independent inputs/outputs (Y0 and Y1), a common input/output (Z) and a digital enable input (E).

When E is HIGH, the switch is turned off. 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 the select and enable inputs makes the circuit tolerant of slower input rise

and fall times across the entire VCC range from 1.65 V to 5.5 V.

2. Features and benefits
