KK74HC258A Datasheet | Kodenshi AUK Group

TECHNICAL DATA Quad 2-Input Data Selectors/Multiplexer with 3-State Outputs High-Performance Silicon-Gate CMOS The KK74HC258A is identical in pinout to the LS/ALS258. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. This device selects a (4-bit) nibble from either the A or B inputs as determined by the Select input. The nibble is presented at the outputs in inverted form when the Output Enable pin is at a low level. A high level on the Output Enable pin switches the outputs into the high-impedance state. - 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 KK74HC258AN Plastic KK74HC258AD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Output Enable H PIN 16 =VCC PIN 8 = GND L L Select X L H Outputs Y0-Y3 Z A0-A3 B0-B3 X=don’t care Z = high-impedance state A0-A3,B0-B3=the levels of the respective Nibble Inputs ..net 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 m A m A m A m W °C °C Maximum Ratings are those values beyond which damage to the device may occur.
