MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC74HC109 Dual J-K Flip-Flop with Set and Reset High–Performance Silicon–Gate CMOS N SUFFIX PLASTIC PACKAGE 16 The MC74HC109 is identical in pinout to the LS109. The device inputs are CASE 648–08 1 compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device consists of two J–K flip–flops with individual set, reset, and D SUFFIX clock inputs. Changes at the inputs are reflected at the outputs with the next 16 SOIC PACKAGE low–to–high transition of the clock. Both Q and Q outputs are available from CASE 751B–05 1 each flip–flop. • Output Drive Capability: 10 LSTTL Loads ORDERING INFORMATION • Outputs Directly Interface to CMOS, NMOS, and TTL MC74HCXXXN Plastic • Operating Volta
