TC74HC74AP/AF/AFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic www.DataSheet4U.com TC74HC74AP,TC74HC74AF,TC74HC74AFN Dual D-Type Flip Flop Preset and Clear The TC74HC74A is a high speed CMOS D FLIP FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL 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 CLOCK pulse. CLEAR and PRESET are independent of the CLOCK 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. Note: xxxFN (JEDEC SOP) is not available in Japan.
