MM74HC14

Hex Inverting Schmitt Trigger

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 compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.

Features

■Typical propagation delay: 13 ns

■Wide power supply range: 2–6V

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

■Low input current: 1 μA maximum

■Fanout of 10 LS-TTL loads

■Typical hysteresis voltage: 0.9V at VCC = 4.5V

Note 4: For a power supply of 5V ±10% the worst case output voltages (VOH, and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used.
