74AHCT14APW中文资料Hex inverting Schmitt trigger数据手册Nexperia规格书

描述 Description

The 74AHCT14A is a hexadecimal inverter with Schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals
Designed to operate over a VCC range from 4.5 V to 5.5 V, the inputs are TTL compatible. This range allows the device to be used to translate from 3.3 V to 5 V.
This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
