IN74ACT109

TECHNICAL DATA IN74ACT109 Dual J-K Flip-Flop with Set and Reset High-Speed Silicon-Gate CMOS The IN74ACT109 is identical in pinout to the LS/ALS109, HC/HCT109. The IN74ACT109 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 µA; 0.1 µA @ 25°C Outputs Source/Sink 24 mA ORDERING INFORMATION IN74ACT109N Plastic IN74ACT109D 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 .d e e h s a t a . u t4 PIN 16=VCC PIN 8 = GND m o c H H H H L X X 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. 1 www.DataSheet4U.com IN74ACT109 MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per ...
