IN74ACT253

TECHNICAL DATA IN74ACT253 Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Speed Silicon-Gate CMOS The IN74ACT253 is identical in pinout to the LS/ALS253, HC/HCT253. The IN74ACT253 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The Address Inputs select one of four Data Inputs from each multiplexer. Each multiplexer has an active-low Output Enable control and a three-state noninverting output. 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 IN74ACT253N Plastic IN74ACT253D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs A1 X L A0 X L H L H Output Enable H L L L L Output Y Z D0 D1 D2 D3 w w w .d e e h s a t a . u t4 m o c L H H PIN 16 =VCC PIN 8 = GND D0,D1...D3=the level of the respective Data Input Z = high impedance X = don’t care 1 www.DataSheet4U.com IN74ACT253 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...
