DS26C32AT/DS26C32AM Quad Differential Line Receiver
Check for Samples: DS26C32AM,DS26C32AT
1FEATURES DESCRIPTION
The DS26C32A is a quad differential line receiver
2 CMOS Design for Low Power designed to meet the RS-422, RS-423, and Federal
±0.2V Sensitivity over Input Common Mode Standards 1020 and 1030 for balanced and
Voltage Range unbalanced digital data transmission, while retaining
Typical Propagation Delays: 19 ns the low power characteristics of CMOS.
Typical Input hysteresis: 60 mV The DS26C32A has an input sensitivity of 200 mV
over the common mode input voltage range of ±7V.
Inputs Won't Load Line When VCC = 0V The DS26C32A features internal pull-up and pull-
Meets the Requirements of EIA Standard RS- down resistors which prevent output oscillation on
422 unused channels.
TRI-STATE Outputs for Connection to System The DS26C32A provides an enable and disable
Buses function common to all four receivers. It also features
Available in Surface Mount TRI-STATE outputs with 6 mA source and sink
Mil-Std-883C Compliant capability. This product is pin compatible with the
DS26LS32A and the AM26LS32.

(1) 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.
(2) 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 <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
