DESCRIPTION
The 74LVC32A is a low voltage CMOS QUAD
2-INPUT OR GATE fabricated with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
technology. It is ideal for 1.65 to 3.6 V
CC
operations and low power and low noise
applications.
It can be interfaced to 5V signal environment for
inputs in mixed 3.3/5V system.
It has more speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
All inputs and outputs are equipped with
protection circuits against stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.
