| Overview | SN54/74LS109A DUAL JK POSITIVE EDGE-TRIGGERED FLIP-FLOP The SN54/ 74LS109A consists of two high speed completely independent transition clocked JK flip-flops. The clocking operation is independent of . ates are unpredictable if SD and CD go HIGH simultaneously. H, h = HIGH Voltage Level L, I = LOW Voltage Level X = Don’t Care l, h (q) = Lower case letters indicate the state of the referenced input (or output) l, h (q) = one set-up time prior to the LOW to HIGH clock transition. 2 J SD Q 6 14 . |
