74VHCT02AT

The internal circuit is composed of 3 stages

including buffer output, which provide 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.

V_CC(OPR)= 4.5V to 5.5V

PIN AND FUNCTION COMPATIBLEWITH

74 SERIES02

IMPROVED LATCH-UP IMMUNITY

LOWNOISE:V_OLP= 0.8V(Max.)

■

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

DESCRIPTION

The 74VHCT02A is an advanced high-speed

CMOS QUAD 2-INPUT NOR GATE fabricated

with sub-micron silicon gate and double-layer

metal wiring C²MOS technology.
