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.
