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

DESCRIPTION
The 74VHCT32A is an advanced high-speed
CMOS QUAD 2-INPUT OR 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
