description

The ′F257 is designed to multiplex signals from

4-bit data sources to 4-output data lines in

bus-organized systems. The 3-state outputs will

not load the data lines when the output enable

(OE) input is at a high logic level.

The SN54F257 is characterized for operation over

the full military temperature range of −55°C to

125°C. The SN74F257 is characterized for

operation from 0°C to 70°C.
