DESCRIPTION
The 74VHC132 is an advanced high-speed
CMOS QUAD 2-INPUT SCHMITT NAND GATE
fabricated with sub-micron silicon gate and
double-layer metal wiring C
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
PIN CONNECTION AND IEC LOGIC SYMBOLS

regard to the supply voltage. This device can be
used to interface 5V to 3V.
Pin configuration and function are the same as
those of the VHC00 but the VHC132 has
hysteresis.
This together with its schmitt trigger function
allows it to be used on line receivers with slow
rise/fall input signals.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
