74VHCT14A

HEX SCHMITT inverter

Features

■ High speed: tPD = 5.5ns (typ.) at VCC = 5V

■ Low power dissipation:

ICC = 2 µA (Max.) at TA = 25°C

■ Typical hysteresis: Vh = 0.7V at VCC = 4.5V

■ Power down protection on inputs & outputs

■ Symmetrical output impedance:

|IOH| = IOL = 8 mA (Min)

■ Balanced propagation delays:

tPLH ≅ tPHL

■ Operating voltage range:

VCC(Opr) = 4.5V to 5.5V

■ Pin and function compatible with

74 series 14

■ Improved latch-up immunity

■ Low noise: VOLP = 0.8V (Max.)

Description

The 74VHCT14A is an advanced high-speed

CMOS HEX SCHMITT inverter fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology.

The internal circuit is composed of 3 stages

including buffer output, which provides high noise

immunity and stable output.

Power down protection is provided on all inputs

and outputs and 0 to 7V can be accepted on

inputs with no regard to the supply voltage. This

device can be used to interface 5V to 3V since all

inputs are equipped with TTL threshold.

Pin configuration and function are the same as

those of the 74VHC04 but the 74VHC14 has

hysteresis.

This together with its schmitt trigger function

allows it to be used on line receivers with slow

rise/fall input signals.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
