The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D-type flip-flop (refer to F74 data sheet) by connecting the J and K inputs. 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 Ordering Code: Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
