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 function are the same as the VHC00 but the inputs have hysteresis between the positive-going and negative-going input thresholds, which are capable of transforming slowly changing input signals into sharply defined, jitter-free output 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 mismatched supply and input voltages.
