TC7WH32FU/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7WH32FU,TC7WH32FK 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. TC7WH32FU TC7WH32FK Features * High speed: tpd = 3.8 ns (typ.) at VCC = 5 V * Low power dissipation: ICC = 2 A (max) at Ta = 25C * High noise immunity: VNIH = VNIL = 28% VCC (min) * * Power down protection is provided on all inputs.
