74HC1G14; 74HCT1G14
Inverting Schmitt trigger
Rev. 6 — 27 December 2012
Product data sheet
1. General description
74HC1G14 and 74HCT1G14 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 HC device has CMOS input switching levels and supply voltage range 2 V to 6 V.
The HCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.
The standard output currents are half of those of the 74HC14 and 74HCT14.
2. Features and benefits
Symmetrical output impedance
High noise immunity
Low power dissipation
Balanced propagation delays
SOT353-1 and SOT753 package options
