TC74VHC32FT集成電路（IC）的門反相器規(guī)格書PDF中文資料

The TC74VHC32 is an advanced high speed CMOS 2 - INPUT

OR GATE fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low

power dissipation.

The internal circuit is composed of 4 stages including buffer

output, which provide high noise immunity and stable output.

An input protection circuit ensures that 0 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 back up.

This circuit prevents device destruction due to mismatched

supply and input voltages.
