DESCRIPTION

The 74VHC32 is a n advanced high-speed CM OS
QUAD 2-INPUT OR GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C

2

MOS technology.
The internal circuit is composed of 2 stages
including buffer ou tput, 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 interface 5V to 3V.
All inputs and outputs are equipped with
protection circuits against stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.

CAPACITIVE CHARACTERISTICS

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without

load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I

CC(opr)

= CPD x VCC x fIN + ICC/4 (per gate)
