General Description
Features
Y
High differential or common-mode input voltage ranges
The DS26LS32 and DS26LS32A are quad differential line
receivers designed to meet the RS-422, RS-423 and Feder-
al Standards 1020 and 1030 for balanced and unbalanced
digital data transmission.

6k minimum input impedance
Both the DS26LS32A and DS26LS33A differ in function
from the popular DS26LS32 and DS26LS33 in that input
pull-up and pull-down resistors are included which prevent
output oscillation on unused channels.

Operation from a single 5V supply
Each version provides an enable and disable function com-
mon to all four receivers and features TRI-STATE outputs
with 8 mA sink capability. Constructed using low power
Schottky processing, these devices are available over the
full military and commerical operating temperature ranges.

put enables for receiving directly onto a data bus

Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device operation.
Note 2: All currents into device pins are shown as positive, all currents out of device pins are shown as negative, all voltages are referenced to ground, unless
otherwise specified. All values shown as max or min are so classified on absolute value basis.
