MM74HC14

Hex Inverting Schmitt Trigger

Features

■

Typical propagation delay: 13ns

■

Wide power supply range: 2V–6V

■

Low quiescent current: 20µA maximum (74HC Series)

■

Low input current: 1µA maximum

■

Fanout of 10 LS-TTL loads

■

Typical hysteresis voltage: 0.9V at V

= 4.5V

General Description

The MM74HC14 utilizes advanced silicon-gate CMOS

technology to achieve the low power dissipation and

high noise immunity of standard CMOS, as well as the

capability to drive 10 LS-TTL loads.

The 74HC logic family is functionally and pinout compat-

ible with the standard 74LS logic family. All inputs are

protected from damage due to static discharge by inter-

nal diode clamps to V

and ground.

Ordering Information

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.

All packages are lead free per JEDEC: J-STD-020B standard.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
