CMOS Digital Integrated Circuits Silicon Monolithic TC74AC74FT TC74AC74FT 1. Functional Description • Dual D-Type Flip-Flop with Preset and Clear 2. General The TC74AC74FT is an advanced high speed CMOS D-FLIP FLOP 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 signal level applied to the D INPUT is transferred to Q OUTPUT during the positive going transition of the CK pulse. CLR and PR are independent of the CK and are accomplished by setting the appropriate input to an "L" level. All inputs are equipped with protection circuits against static discharge or transient excess voltage. 3.
