Dual D-Type Positive Edge-Triggered Flip-Flop

the outputs until the next rising edge of the Clock Pulse

input.

General Description

The F74 is a dual D-type flip-flop with Direct Clear and Set

inputs and complementary (Q, Q) outputs. Information at

the input is transferred to the outputs on the positive edge

of the clock pulse. Clock triggering occurs at a voltage level

of the clock pulse and is not directly related to the transition

time of the positive-going pulse. After the Clock Pulse input

threshold voltage has been passed, the Data input is

locked out and information present will not be transferred to

Asynchronous Inputs:

LOW input to S_Dsets Q to HIGH level

LOW input to C_Dsets Q to LOW level

Clear and Set are independent of clock

Simultaneous LOW on C_Dand S_D

makes both Q and Q HIGH
