This data selector/multiplexer contains inverters
and drivers to supply full data selection to the four
output gates. A separate output-enable (OE) input
is provided. A 4-bit word is selected from one of
two sources and is routed to the four outputs. The
74AC11158 provides true data.
The 74AC11158 is characterized for operation
from −40°C to 85°C.
