| IN74HCT109 DUAL J-K FLIP-FLOP WITH SET AND RESET High-Performance Silicon-Gate CMOS The IN74HCT109 is identical in pinout to the LS/ALS109. The IN74HCT109 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 IN74HCT109N Plastic IN74HCT109D 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. 3 IN74HCT109 AC ELECTRICAL CHARACTERISTICS(VCC=5.5 V 10%, CL=50pF,Input tr=tf=6.0 ns) Guaranteed Limit Unit Symbol Parameter 85 125 25 C to C C -55C fmax Maximum Clock Frequency (50% Duty 30 24 20 MHz Cycle) (Figures 1 and 4) 35 44 53 ns tPLH, Maximum Propagation Delay, Clock to Q tPHL or Q (Figures 1 and 4) 46 58 69 ns tPHL Maximum Propagation Delay , Set or Reset to Q or Q (Figures 2 and 4) tTLH, tTHL Maximum Output Transition Time, Any 15 19 22 ns Output (Figures 1 and 4) CIN Maximum Input Capacitance 10 10 10 pF Power Dissipation Capacitance (Per FlipFlop) Used to determine the no-load dynamic power consumption: PD=CPDVCC2f+ICCVCC+ICCVCC Typical @25C,VCC=5.0 V 60 CPD pF TIMING REQUIREMENTS (VCC=5.5 V 10%, CL=50pF,Input tr=tf=6.0 ns) Guaranteed Limit Symbol Parameter 25 C to 85C 125C -55C tSU Minimum Setup Time, J 20 25 30 or K to Clock (Figure 3) th Minimum Hold Time, 5 5 5 Clock to J or K (Figure 3) 5 5 5 trec Minimum Recovery Time, Set or Reset Inactive to Clock (Figure 2) tw Minimum Pulse Width, 16 20 24 Set or Reset (Figure 2) tw Minimum Pulse 16 20 24 Width,Clock (Figure 1) tr, tf Maximum Input Rise and 500 500 500 Fall Times (Figure 1) Unit ns ns ns ns ns ns 4 IN74HCT109 Figure 1.
