| TECHNICAL DATA IN74ACT125 Quad 3-State Noninverting Buffers High-Speed Silicon-Gate CMOS The IN74ACT125 is identical in pinout to the LS/ALS125, HC/HCT125. The IN74ACT125 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The IN74ACT125 noninverting buffers are designed to be used with 3state memory address drivers, clock drivers, and other bus-oriented systems. The devices have four separate output enables that are active-low. * 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 IN74ACT125N Plastic IN74ACT125D SOIC TA = -40 to 85 C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs A H L PIN 14 =VCC PIN 7 = GND X OE L L H Output Y H L Z X = don't care Z = high impedance 1 IN74ACT125 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. 2 IN74ACT125 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol VIH VIL VOH Parameter Minimum HighLevel Input Voltage Maximum Low Level Input Voltage Minimum HighLevel Output Voltage Test Conditions VOUT= VCC-0.1 V VOUT=0.1 V IOUT -50 A VIN=VIH IOH=-24 mA IOH=-24 mA VOL Maximum LowLevel Output Voltage IOUT 50 A * * Guaranteed Limits 25 C 2.0 2.0 0.8 0.8 4.4 5.4 3.86 4.86 0.1 0.1 0.36 0.36 0.1 -40C to 85C 2.0 2.0 0.8 0.8 4.4 5.4 3.76 4.76 0.1 0.1 0.44 0.44 1.0 1.5 0.5 5.0 A mA A V Unit V V V V 4.5 5.5 4.5 5.5 4.5 5.5 4.5 5.5 4.5 5.5 4.5 5.5 5.5 5.5 5.5 VIN= VIL IOL=24 mA IOL=24 mA VIN=VCC or GND VIN=VCC - 2.1 V IIN ICCT IOZ Maximum Input Leakage Current Additional Max.
