TC74AC32FT中文资料东芝数据手册PDF规格书

The TC74AC32 is an advanced high speed CMOS 2-INPUT OR GATE fabricated with silicon gate and double-layer metal wiring 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 2 stages including buffer output, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features
