Overview

SL74HC109 Dual J -K Flip-Flop with Set and Reset High-Performance Silicon-Gate CMOS The SL74HC109 is identical in pinout to the LS/ALS109.
The device inputs are compatible with standard CMOS outputs, with pullup resistors, they are compatible with LS/ALSTTL outputs.
This device consists of two J-K flip-flops with individual set, reset, and clock inputs.
Changes at the inputs are reflected at the outputs with the next low-to-high transition of the clock.
Both Q to Q outputs are available from each flip-flop.
• Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.
0 to 6.
0 V • Low Input Current: 1.
0 µ A • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION SL74HC109N Plastic SL74HC109D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Set L H L H H H H PIN 16=VCC PIN 8 = GND H Reset H L L H H H H H L Clock X X X J X X X L H L H X K X X X L L H H X Outputs Q H L H * Q L H H * L H Toggle No Change H L No Change X = Don’t care * Both outputs will remain high as long as Set and Reset are low, but the output states are unpredictable if Set and Reset go high simultaneously.
