SN74HCS74/SN74HCS74-Q1 D-Type Flip-Flops

Texas Instruments SN74HCS74/SN74HCS74-Q1 D-Type Flip-Flops feature a wide operating range, low power consumption, and Schmitt-trigger inputs, allowing for slow or noisy input signals. A low level at the preset (PRE) input sets the output high, or the clear (CLR) input resets the output low. The asynchronous preset and clear functions are not dependent on the levels of the other inputs.
