Hex inverting Schmitt trigger

Rev. 2 — 26 October 2016

Product data sheet

1. General 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 V_CCrange 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 I_OFF

The I_OFFcircuitry disables the output, preventing the damaging backflow current through

the device when it is powered down.

2. Features and benefits

 Direct interface with TTL levels

 Supply voltage range from 4.5 V to 5.5 V

 Typical t_pdof 3.7 ns at 5 V

 Typical V_OL(p)< 0.8 V at V_CC= 5 V, T_amb= 25 C

 Typical V_OH(v)> 2.3 V at V_CC= 5 V, T_amb= 25 C

 Supports mixed-mode voltage operation on all ports

 I_OFFcircuitry provides partial Power-down mode operation

 Latch-up performance exceeds 250 mA per JESD 78 Class II

 ESD protection:

 HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 3 kV

 MM JESD22-A115-A exceeds 200 V

 CDM JESD22-C101E exceeds 2 kV

 Specified from 40 C to +85 C and from 40 C to +125 C
