FEATURES
DESCRIPTION
•
The DS26LS32 and DS26LS32A are quad differential
line receivers designed to meet the RS-422, RS-423
and Federal Standards 1020 and 1030 for balanced
and unbalanced digital data transmission.

Operation From a Single 5V Supply
TRI-STATE Outputs, with Choice of
Complementary Output Enables for Receiving
Directly onto a Data Bus
The DS26LS32 and DS26LS32A have an input
sensitivity of 200 mV over the input voltage range of
±7V and the DS26LS33 has an input sensitivity of
500 mV over the input voltage range of ±15V.
The DS26LS32A differs 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.
Each version provides an enable and disable function
common 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 commercial
operating temperature ranges.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

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.
All typical values are VCC = 5V, TA = 25°C.
Only one output at a time should be shorted.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
