Dual 2-Input OR Gate

The TC7WH32 is an advanced high speed CMOS 2-Input OR

Gate fabricated with silicon gate CMOS 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 7 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

· High speed: tpd = 3.8 ns (typ.) at VCC = 5 V

· Low power dissipation: ICC = 2 µA (max) at Ta = 25°C

· High noise immunity: VNIH = VNIL = 28% VCC (min)

· Power down protection is provided on all inputs.

· Balanced propagation delays: tpLH ~

-tpHL

· Wide operating voltage range: VCC (opr) = 2~5.5 V
