| TECHNICAL DATA IN74HCT109A Dual J-K Flip-Flop with set and Reset High-Performance Silicon-Gate CMOS The IN74HCT109A is identical in pinout to the LS/ALS109. The IN74HCT109A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. 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. * TTL/NMOS Compatible Input Levels * Outputs Directly Interface to CMOS, NMOS, and TTL * Operating Voltage Range: 4.5 to 5.5 V * Low Input Current: 1.0 A ORDERING INFORMATION IN74HCT109AN Plastic IN74HCT109AD SOIC TA = -55 to 125 C for all packages.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND(VIN or VOUT)VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
