including buffer output, which provides high noise

immunity and stable output.

Power down protection is provided on all inputs

and 0 to 7V can be accepted on inputs with no

regard to the supply voltage. This device can be

used to interface5V to 3V.

OPERATING VOLTAGERANGE:

V_CC(OPR)= 2V to 5.5V

PIN AND FUNCTION COMPATIBLEWITH

74 SERIES27

IMPROVED LATCH-UP IMMUNITY

DESCRIPTION

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

The 74VHC27 is an advanced high-speed CMOS

TRIPLE 3-INPUT NOR GATE fabricated with

sub-micron silicon gate and double-layer metal

wiring C²MOS technology.

The internal circuit is composed of 3 stages
