DUAL D-TYPE POSITIVE
EDGE-TRIGGERED FLIP-FLOP
The MC54/74F74 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 the outputs until the next rising edge of the Clock Pulse input.
• ESD > 4000 Volts

Asynchronous Inputs:
LOW Input to SD sets Q to HIGH level
LOW Input to CD sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on CD and SD makes both Q and Q HIGH
H = HIGH Voltage Level
L = LOW Voltage Level
tn = Bit time before clock pulse
tn + 1 = Bit time after clock pulse
