| IN74ACT534 OCTAL 3-STATE INVERTING D FLIP-FLOP High-Speed Silicon-Gate CMOS The IN74ACT534 is identical in pinout to the LS/ALS534, HC/HCT534. The IN74ACT534 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. Data meeting the setup time is clocked, in inverted form, to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, the outputs are forced to the high impedance state. Thus, data may be stored even when the outputs are not enabled. * 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 LOGIC DIAGRAM * * * * ORDERING INFORMATION IN74ACT534N Plastic IN74ACT534DW SOIC TA = -40 to 85 C for all packages PIN ASSIGNMENT FUNCTION TABLE Output Enable L L L H Inputs Clock D H L X X X Output Q L H no change Z PIN 20=VCC PIN 10 = GND L,H, X = don't care Z = high impedance 1 IN74ACT534 MAXIMUM RATINGS* Symbol Parameter Value Unit VCC DC Supply Voltage (Referenced to GND) -0.5 to +7.0 V VIN DC Input Voltage (Referenced to GND) -0.5 to VCC +0.5 V VOUT DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V IIN DC Input Current, per Pin mA 20 IOUT DC Output Sink/Source Current, per Pin mA 50 ICC DC Supply Current, VCC and GND Pins mA 50 PD Power Dissipation in Still Air, Plastic DIP+ 750 mW SOIC Package+ 500 Tstg Storage Temperature -65 to +150 C 260 TL Lead Temperature, 1 mm from Case for 10 C Seconds (Plastic DIP or SOIC Package) * 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. 2 IN74ACT534 DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) Guaranteed VCC Limits Symbol Parameter Test Conditions V 25 C -40C to 85C VIH Minimum High- VOUT= 0.1 V or VCC-0.1 4.5 2.0 2.0 Level Input V 5.5 2.0 2.0 Voltage VIL Maximum Low - VOUT= 0.1 V or VCC-0.1 4.5 0.8 0.8 Level Input V 5.5 0.8 0.8 Voltage VOH Minimum High- IOUT -50 A 4.5 4.4 4.4 Level Output 5.5 5.4 5.4 Voltage * VIN=VIH or VIL 3.76 3.86 IOH=-24 mA 4.5 4.76 4.86 5.5 IOH=-24 mA VOL Maximum Low- IOUT 50 A 4.5 0.1 0.1 Level Output 5.5 0.1 0.1 Voltage * VIN= VIH or VIL 0.44 0.36 IOL=24 mA 4.5 0.44 0.36 5.5 IOL=24 mA IIN Maximum Input VIN=VCC or GND 5.5 0.1 1.0 Leakage Current 5.5 1.5 Additional Max.
