74L VC32AQuad 2-input OR gate
FEA TURES
•Wide supply voltage range of 1.2 V to 3.6 V
•In accordance with JEDEC standard no. 8-1A.
•Inputs accept voltages up to 5.5 V
•CMOS low power consumption
•Direct interface with TTL levels
DESCRIPTION
The 74LVC32A is a high-performance, low-power, low-voltage
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
Inputs can be driven from either 3.3V or 5V devices. This feature
allows the use of these devices as translators in a mixed 3.3V/5V
environment.
The 74LVC32A provides the 2-input OR function.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
