QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS/MULTIPLEXERS
WITH 3-STATE OUTPUTS
SDAS124C – APRIL 1982 – REVISED AUGUST 1996
1
POST OFFICE BOX 655303
DALLAS, TEXAS 75265
3-State Outputs Interface Directly With
System Bus
Provide Bus Interface From Multiple
Sources in High-Performance Systems
Package Options Include Plastic
Small-Outline (D) Packages, Ceramic Chip
Carriers (FK), and Standard Plastic (N) and
Ceramic (J) 300-mil DIPs
description
These data selectors/multiplexers are designed
to multiplex signals from 4-bit data sources to
4-output data lines in bus-organized systems. The
3-state outputs do not load the data lines when the
output-enable (OE) input is at a high logic level.
The SN54ALS257A and SN54ALS258A are
characterized for operation over the full military
temperature range of –55
°
C to 125
°
C. The
SN74ALS257A, SN74ALS258A, SN74AS257,
and SN74AS258 are characterized for operation
from 0
°
C to 70
°
C.
