74VHC132
Quad 2-Input NAND Schmitt Trigger
General Description
The VHC132 is an advanced high speed CMOS 2-input
NAND Schmitt Trigger Gate fabricated with silicon gate
CMOS technology. It achieves the high-speed operation
similar to Bipolar Schottky TTL while maintaining the
CMOS low power dissipation. Pin configuration and func-
tion are the same as the VHC00 but the inputs have hyster-
esis between the positive-going and negative-going input
thresholds, which are capable of transforming slowly
changing input signals into sharply defined, jitter-free out-
put signals. Thus greater noise margin then conventional
gates is provided. An input protection circuit ensures that
0V to 7V can be applied to the input pins without regard to
the supply voltage. This device can be used to interface 5V
to 3V systems and two supply systems such as battery
backup. This circuit prevents device destruction due to mis-
matched supply and input voltages.
