description
The
′ALS857 are hextuple 2-line to 1-line
multiplexers with 3-state outputs. The devices can
provide either true (COMP low) or inverted
(COMP high) data at the Y outputs. In addition, the
′ALS857 perform the logical AND function (A B)
and the clear function as well. The four modes of
operation are:
Select A-data inputs
Select B-data inputs
AND A inputs with B inputs
Clear
In either of the first two modes, OPER = 0 is high
if all the selected A or B inputs are low. The six Y
outputs and the OPER = 0 output are all 3-state
and rated at 12-mA and 24-mA IOL for the
SN54ALS857 and SN74ALS857, respectively. All
outputs can be placed in the high-impedance state
by applying a high level to the COMP, S0, and S1
inputs simultaneously.
The SN54ALS857 is characterized for operation over the full military temperature range of – 55
°C to 125°C. The
SN74ALS857 is characterized for operation from 0
°C to 70°C.
