The TC74AC05 is an advanced high speed CMOS INVERTER 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. Pin configuration and function are the same as the TC74AC04, but the TC74AC05 has high performance MOS N-channel transistor (open-drain) outputs.This device can, therefore, with a suitable pull-up resistors, be used in wired-OR, LED drive and other applications. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
