IN74HC257規(guī)格書詳情
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
