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.
