operation.

The ’AHC257 devices are designed to multiplex

signals from 4-bit data sources to 4-output data

lines in bus-organized systems. The 3-state

outputs do not load the data lines when the

output-enable (OE) input is at a high logic level.

To ensure the high-impedance state during power

up or power down, OE should be tied to V

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking

capability of the driver.

NC – No internal connection

The SN54AHC257 is characterized for operation

over the full military temperature range of –55°C

to 125°C. The SN74AHC257 is characterized for

operation from –40°C to 85°C.
