74LCX74 Dual D-Type Flip-Flop with Preset & Clear With 5V Tolerant Input

The 74LCX74 is a low voltage CMOS dual D-type flip flop with preset and clear non inverting fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for inputs.

A signal on the D INPUT is transferred to the Q OUTPUT during the positive going transition of the clock pulse.

CLR and PR are independent of the clock and accomplished by a low setting on the appropriate input.

It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
