Description
●The Harris CD74AC74 and CD74ACT74 dual D-type, positive 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 output 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.
