IMPROVED LATCH-UP IMMUNITY
LOW NOISE: V
= 0.8V (MAX.)
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 interface 5V to 3V.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

DESCRIPTION
The 74VHC02 is an advanced high-speed CMOS
QUAD 2-INPUT NOR GATE fabricated with
sub-micron silicon gate and double-layer metal
2
wiring C MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which provides high noise
immunity and stable output.

1) C is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
PD
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I
