IN74HC253A

TECHNICAL DATA IN74HC253A Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Performance Silicon-Gate CMOS The IN74HC253A is identical in pinout to the LS/ALS253. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. 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. Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 µA High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION IN74HC253AN Plastic IN74HC253AD SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs A1 X L L H H A0 X L H L H OE 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 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 IN74HC253A 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...
