74VHCT14A

Hex Schmitt Inverter

General Description

The VHCT14A is an advanced high speed CMOS Hex

Schmitt Inverter fabricated with silicon gate CMOS technol-

ogy. The VHCT14A contains six independent inverters

which are capable of transforming slowly changing input

signals into sharply defined, jitter-free output signals.

Protection circuits ensure that 0V to 7V can be applied to

the input pins without regard to the supply voltage and to

the output pins with VCC 0V. These circuits prevent

device destruction due to mismatched supply and input/

output voltages. This device can be used to interface 3V to

5V systems and two supply systems such as battery

backup.

Features

s High speed: tPD 5.0 ns (typ) at TA 25qC

s High noise immunity: VIH 2.0V, VIL 0.8V

s Power down protection is provided on all inputs and out-

puts

s Low noise: VOLP 1.0V (max)

s Low power dissipation:

ICC 2 PA (max) @ TA 25qC

s Pin and function compatible with 74HCT14
