description
These devices are designed to multiplex signals from four-bit data sources to four-output date
lines in bus-organized systems. The 3-state outputs will not load the data lines when the output
control pin ( G ) is at a high-logic level.
The SN54HC257 and SN54HC258 are characterized for operation over the full military tempera-
ture range of -55
