MM74HCT14
Hex Inverting Schmitt Trigger
General Description
The MM74HCT14 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 74HCT logic family is functionally and pinout compati-
ble with the standard 74LS logic family. All inputs are pro-
tected from damage due to static discharge by internal
diode clamps to VCC and ground.
Features
s Typical propagation delay: 13 ns
s Wide power supply range: 2–6V
s Low quiescent current: 10 µA maximum
s Low input current: 1 µA maximum
s Fanout of 10 LS-TTL loads
s Typical hysteresis voltage: 0.9V at VCC = 4.5V
s TTL, LS pin-out and input threshold compatible

Note 3: 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 cur-
rent (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used.
