| TECHNICAL DATA IN74ACT112 Dual J-K Flip-Flop with Set and Reset High-Speed Silicon-Gate CMOS The IN74ACT112 is identical in pinout to the LS/ALS112, HC/HCT112. The IN74ACT112 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. Each flip-flop is negative-edge clocked and has active-low asynchronous Set and Reset inputs. * 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; 0.1 A @ 25C * Outputs Source/Sink 24 mA ORDERING INFORMATION IN74ACT112N Plastic IN74ACT112D SOIC TA = -40 to 85 C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Set L H L H H H H H H H PIN 16=VCC PIN 8 = GND Reset H L L H H H H H H H L H Clock X X X J X X X L L H H X X X K X X X L H L H X X X Outputs Q H L L * Q L H L* H L No Change L H Toggle No Change No Change No Change * Both outputs will remain low as long as Set and Reset are low, but the output states are unpredictable if Set and Reset go high simultaneously X = Don't Care Rev. 00 IN74ACT112 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 Pin DC Output Sink/Source Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -0.5 to VCC +0.5 -0.5 to VCC +0.5 20 50 50 750 500 -65 to +150 260 Unit V V V mA mA mA mW C C Maximum Ratings are those values beyond which damage to the device may occur.

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.
