TC74HC74AF Description

Short technical summary and product information.

The Toshiba TC74HC74AF is a high-speed CMOS dual D-type flip-flop fabricated with silicon gate C2MOS technology. It achieves high-speed operation similar to LSTTL while maintaining low CMOS power dissipation.

 

The signal level applied to the D input is transferred to the Q output during the positive-going transition of the clock pulse. The CLEAR and PRESET functions are independent of the clock and are accomplished by setting the appropriate input to a low level. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

 

Key electrical characteristics include a maximum clock frequency of 77 MHz at 5 V, a low quiescent current of 2 μA (max) at 25°C, and high noise immunity. The device supports a wide operating voltage range from 2 V to 6 V and has an output drive capability of 10 LSTTL loads.

 

Available in SOP14 and DIP14 packages, the TC74HC74AF operates within an ambient temperature range of -40°C to 85°C. Its symmetrical output impedance and balanced propagation delays contribute to reliable performance in digital circuits.
