1 / 5 page TECHNICAL DATA 321 Quad 2-Input Data Selector/Multiplexer with 3-State Outputs High-Performance Silicon-Gate CMOS The IN74HC257 is identical in pinout to the LS/ALS257. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible 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 noninverted from 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 IN74HC257 ORDERING INFORMATION IN74HC257N Plastic IN74HC257D SOIC TA = -55° to 125° C for all packages FUNCTION TABLE Inputs Outputs Output Enable Select Y0-Y3 HX Z LL A0-A3 LH B0-B3 X=don’t care Z = high-impedance state A0-A3,B0-B3=the levels of the respective Nibble Inputs LOGIC DIAGRAM PIN 16 =VCC PIN 8 = GND PIN ASSIGNMENT |
