description

These monolithic, positive-edge-triggered flip-flops

utilize TTL circuitry to implement D-type flip-flop logic.

All have a direct clear input, and the ‘175, ‘LS175, and

$175 feature complementary outputs from each flip-

flop.

Information at the D inputs meeting the setup time

requirements is transferred to the Q outputs on the

positive-going edge of the clock pulse. Clock triggering

occurs at a particular 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.

These circuits are fully compatible for use with most

TTL circuits.
