CMOS Digital Integrated Circuits Silicon Monolithic
74VHC32FT
1. Functional Description
•
Quad 2-Input OR Gate
2. General
The 74VHC32FT is an advanced high speed CMOS 2-INPUT OR GATE fabricated with silicon gate C
2
MOS
technology.
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS
low power dissipation.
The internal circuit is composed of 4 stages including buffer output, which provide high noise immunity and
stable output.
An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply
voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.

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).
Note 1: 180 mW in the range of T

.
From T

a derating factor of -3.25 mW/ shall be
applied until 50 mW.
