74LVC14A
Hex inverting Schmitt trigger with 5 V tolerant input
Rev. 8 — 29 April 2021
Product data sheet
1. General description
The 74LVC14A is a hex inverter with Schmitt-trigger inputs. 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.
