Dual D-Type Positive Edge-Triggered Flip-Flop
Description
The HD74AC74 is a dual D-type flip-flop with Asynchronous 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.
Features
Asynchronous Inputs:
Low input to
S
D
(Set) sets Q to High level
Low input to
C
D
(Clear) sets Q to Low level
Clear and Set are independent of clock
Simultaneous Low on
C
D
and
S
D
makes both Q and
Q
High
Outputs Source/Sink 24 mA
