A10872 - MC74HC257N Quad 2-Input Data Slector/Multiplexer (Motorola)
The MC74HC257N is identical in pinout to the LS257. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL 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 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. The MC74HC257N is similar in function to the HC157 which do not have 3?state outputs.
Features:
Output Drive Capability: 15 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1 mA
High Noise Immunity Characteristic of CMOS Devices
16 pin DIP. Manufactured by Motorola.
