2 / 5 page January 1995 2 Philips Semiconductors Product specification Dual JK flip-flop HEF4027B flip-flops DESCRIPTION The HEF4027B is a dual JK flip-flop which is edge-triggered and features independent set direct (SD), clear direct (CD), clock (CP) inputs and outputs (O,O). Data is accepted when CP is LOW, and transferred to the output on the positive-going edge of the clock. The active HIGH asynchronous clear-direct (CD) and set-direct (SD) are independent and override the J, K, and CP inputs. The outputs are buffered for best system performance. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times. Fig.1 Functional diagram. Fig.2 Pinning diagram. FUNCTION TABLES Notes 1. H = HIGH state (the more positive voltage) L = LOW state (the less positive voltage) X = state is immaterial = positive-going transition On + 1 = state after clock positive transition PINNING FAMILY DATA, IDD LIMITS category FLIP-FLOPS See Family Specifications INPUTS OUTPUTS SD CD CP J K O O HL X X X H L LH X X X L H HH X X X H H INPUTS OUTPUTS SD CD CP J K On + 1 On + 1 L L L L no change LL H L H L LL L H L H LL H H On On J,K synchronous inputs CP clock input (L to H edge-triggered) SD asynchronous set-direct input (active HIGH) CD asynchronous clear-direct input (active HIGH) O true output O complement output HEF4027BP(N): 16-lead DIL; plastic (SOT38-1) HEF4027BD(F): 16-lead DIL; ceramic (cerdip) (SOT74) HEF4027BT(D): 16-lead SO; plastic (SOT109-1) ( ): Package Designator North America |
