Dual 4-Input AND Gate

The TC74VHC21 is an advanced high speed CMOS 4-INPUT

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 a buffer

output, which provide high noise immunity and stable output.

An input protection circuit ensures that 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

• Power down protection is provided on all inputs.

• Pin and function compatible with 74ALS21

Note: xxxFN (JEDEC SOP) is not available in

Japan.
