MM74HC74A: Dual D-Type Flip-Flop with Preset and Clear

The MM74HC74A utilizes advanced silicon-gate CMOS technology to achieve operating speeds similar to the equivalent LS-TTL part. It possesses the high noise immunity and low power consumption of standard CMOS integrated circuits, along with the ability to drive 10 LS-TTL loads. This flip-flop has independent data, preset, clear, and clock inputs and Q and Q# outputs. The logic level present at the data input is transferred to the output during the positive-going transition of the clock pulse. Preset and clear are independent of the clock and accomplished by a low level at the appropriate input. The 74HC logic family is functionally and pinout compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.
