SN54F251B 1-of-8 Data Selectors/Multiplexers

These data selectors/multiplexers contain full binary decoding to select one of eight data sources and feature strobe-controlled complementary outputs. The 3-state outputs can interface with and drive data lines of busorganized systems. When the strobe (G) input is high, both outputs are in a high-impedance state in which both the upper and lower transistors.

Features

f, and the output neither drives nor loads the bus significantly. The SN54F251B is characterized for operation over the full military temperature range of − 55°C to 125°C. The SN74F251B is characterized for operation from 0°C to 70°C. SN54F251B . . .
