Description
The Harris CD74AC74 and CD74ACT74 dual D-type, posi-
tive edge triggered flip-flops use the Harris ADVANCED
CMOS technology. These flip-flops have independent DATA,
SET, RESET, and CLOCK inputs and Q and Q outputs. The
logic level present at the data input is transferred to the out-
put during the positive going transition of the clock pulse.
SET and RESET are independent of the clock and are
accomplished by a low level at the appropriate input.
