Description

The MM74HC74A utilizes advanced silicon-gate CMOS technology to achieve operating speeds similar to the equivalent LS-TTL part. MM74HC74A possesses the high noise immu- nity and low power consumption of standard CMOS inte-
grated circuits, along with the ability to drive 10 LS-TTL loads.

This flip-flop MM74HC74A 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.
