产品概述
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 bus-organized systems. When the strobe (G\) input
is high, both outputs are in a high-impedance state in which both the
upper and lower transistors of each totem-pole output are off, 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. D0, D1,...D7 = the level of the respective D input.
