description

The ´ALS857 are hextuple 2-line to 1-line multiplexers with3-state outputs. The devices can provide either true (COMP low) orinverted (COMP high) data at the Y outputs. In addition, the´ALS857 perform the logical AND function (A • B) and the clearfunction 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 theselected A or B inputs are low. The six Y outputs and the OPER = 0output are all 3-state and rated at 12-mA and 24-mA I_OLfor the SN54ALS857 and SN74ALS857, respectively. All outputs can beplaced in the high-impedance state by applying a high level to theCOMP, S0, and S1 inputs simultaneously.

The SN54ALS857 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74ALS857 is characterized for operation from 0°C to 70°C.
