TC74VHCT74AFT Description

Short technical summary and product information.

The TC74VHCT74AFT from Toshiba is a dual D-Type flip-flop built with silicon gate C2MOS technology, achieving high-speed operation comparable to Bipolar Schottky TTL while maintaining low CMOS power dissipation. The D input signal is transferred to the Q output on the positive-going transition of the clock pulse. Independent Clear (CLR) and Preset (PR) functions are available, activated by setting the respective input low.

This device features a maximum clock frequency of 160 MHz at 5V VCC and a low quiescent current of 2 µA maximum at 25°C. Input voltage levels are compatible with TTL outputs, with VIL at 0.8V maximum and VIH at 2.0V minimum. The TC74VHCT74AFT can serve as a level converter for interfacing 3.3V to 5V systems. Input and output circuits include protection to prevent destruction from mismatched supply and I/O voltages.

Available in SOP14 and TSSOP14 surface mount packages, the TC74VHCT74AFT is pin and function compatible with the standard 74 series logic. Its balanced propagation delays (tpLH ≈ tpHL) make it suitable for various digital logic applications requiring reliable flip-flop functionality.
