description
Each of these data selectors/multiplexers
contains inverters and drivers to supply full binary
decoding data selection to the AND-OR gates.
Separate output control inputs are provided for
each of the two four-line sections.
The 3-state outputs can interface with and drive
data lines of bus-organized systems. With all but
one of the common outputs disabled (at a
high-impedance state), the low-impedance of
the single enabled output will drive the bus line
to a high or low logic level. Each output has
its own strobe (G). The outputs are disabled when
G is high.
The 54ACT11253 is characterized for operation
over the full military temperature range of 55
C
to 125
C. The 74ACT11253 is characterized for
operation from 40
C to 85
C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded provided the input and output current ratings are observed.

Not more than one output should be tested at a time, and the duration of the test should not exceed 10 ms.
This is the increase in supply current for each input that is at one of the specified TTL voltage levels rather than 0 V or VCC.
