TC7W74F/FU/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7W74F,TC7W74FU,TC7W74FK D-Type Flip Flop with Preset and Clear The TC7W74 is a high speed C2MOS D Flip Flop fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the C2MOS low power dissipation. The signal level applied to the D INPUT is transferred to Q OUTPUT during the positive going transition of the CLOCK pulse CLEAR and PRESET are independent of the CLOCK and are accomplished by setting the appropriate input to an “L” level Input is equipped with protection circuits against static discharge or transient excess voltage.
