DESCRIPTION
The 74HC1G/HCT1G14 is a
high-speed Si-gate CMOS device.
The 74HC1G/HCT1G14 provides the
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 standard output currents are
