description

These monolithic data selectors/multiplexers

provide full binary decoding to select one of eight

data sources. The strobe (G) input must be at a

low logic level to enable the data

selection/multiplexing function. A high level at the

strobe terminal forces the W output high and the

Y output low.

The SN54F151B is characterized for operation

over the full military temperature range of −55°C

to 125°C. The SN74F151B is characterized for

operation from 0° °C to 70 C.

†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: The input voltage rating may be exceeded provided that the input current rating is observed.
