1. Functional Description
•
Quad 2-Input OR Gate
2. General
The 74HCT32D is a high speed CMOS 2-INPUT OR GATE fabricated with silicon gate C
2
MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power
dissipation.
This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are
compatible with TTL, NMOS and CMOS output voltage levels.
The internal circuit is composed of 4 stages including buffer output, which provide high noise immunity and
stable output.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report
and estimated failure rate, etc).
