Hex Quad D Flip-Flops with Clear

General Description

These positive-edge-triggered flip-flops utilize TTL circuitry

to implement D-type flip-flop logic All have a direct clear

input and the quad (175) versions feature complementary

outputs from each flip-flop

Information at the D inputs meeting the setup time require-

ments is transferred to the Q outputs on the positive-going

edge of the clock pulse Clock triggering occurs at a particu-

lar voltage level and is not directly related to the transition

time of the positive-going pulse When the clock input is at

either the high or low level the D input signal has no effect

at the output
