KK74HCT125A

TECHNICAL DATA KK74HCT125A Quad 3-State Noninverting Buffers High-Performance Silicon-Gate CMOS The KK74HCT125A is identical in pinout to the LS/ALS125. The KK74HCT125A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The KK74HCT125A noninverting buffers are designed to be used with 3-state 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 µA ORDERING INFORMATION KK74HCT125AN Plastic KK74HCT125AD SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs PIN 14 =VCC PIN 7 = GND A H L X OE L L H Output Y H L Z X = don’t care Z = high impedance www.DataSheet4U.net 1 KK74HCT125A 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 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 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±35 ±75 750 500 -65 to +150 260 Unit V V V mA mA mA mW °C °C Maximum Ratings are those values...
