Overview
TECHNICAL DATA IN74AC109 Dual J-K Flip-Flop with Set and Reset High-Speed Silicon-Gate CMOS The IN74AC109 is identical in pinout to the LS/ALS109,HC/HCT109.
The device inputs are compatible with standard CMOS outputs, with pullup resistors, they are compatible with LS/ALS 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 µA; 0.
1 µA @ 25°C • High Noise Immunity Characteristic of CMOS Devices • Outputs Source/Sink 24 mA ORDERING INFORMATION IN74AC109N Plastic IN74AC109D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Set L H L H H Reset H L L H H H H Clock X X X J X X X L H L H K X X X L L H H Outputs Q H L H * Q L H H* H L Toggle No Change H L w w w .
