74AHC1G14; 74AHCT1G14
Inverting Schmitt trigger
Rev. 7 — 18 November 2014
Product data sheet
1. General description
74AHC1G14 and 74AHCT1G14 are high-speed Si-gate CMOS devices. They provide an
inverting buffer function with Schmitt trigger action. These devices are capable of
transforming slowly changing input signals into sharply defined, jitter-free output signals.
The AHC device has CMOS input switching levels and supply voltage range 2 V to 5.5 V.
The AHCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.
2. Features and benefits
Symmetrical output impedance
High noise immunity
ESD protection:
HBM JESD22-A114E: exceeds 2000 V
MM JESD22-A115-A: exceeds 200 V
CDM JESD22-C101C: exceeds 1000 V
Low power dissipation
Balanced propagation delays
SOT353-1 and SOT753 package options
Specified from 40 C to +125 C
3. Applications
Wave and pulse shapers
Astable multivibrators
Monostable multivibrators
