74VHC74MX

The 74VHC74MX from ON Semiconductor is an advanced high-speed CMOS Dual D-Type Flip-Flop. Fabricated with silicon gate CMOS technology, it achieves high-speed operation similar to bipolar Schottky TTL 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 CK pulse. Clear (CLR) and Preset (PR) inputs are independent of the clock and are accomplished by setting the appropriate input LOW.

This device features a maximum clock frequency of 170 MHz (typical) at 25°C and offers high noise immunity with VNIH = VNIL = 28% VCC (minimum). It operates over a supply voltage range of 2V to 5.5V and has a low power dissipation with a quiescent current of 2 µA (maximum) at 25°C. The maximum propagation delay is 9.3 ns at 5V and 50pF. It includes power-down protection on all inputs.

The 74VHC74MX is supplied in a 14-SOIC package with surface mount mounting type. It is pin and function compatible with the 74HC74. The device is Pb-Free, Halogen Free/BFR Free, and RoHS Compliant. An input protection circuit allows 0V to 5.5V to be applied to the input pins without regard to the supply voltage, enabling interfacing between 5V and 3V systems.
