Check for Samples: DS3486
1FEATURES DESCRIPTION
Texas Instruments' quad RS-422, RS-423 receiver
2• Four Independent Receivers features four independent receivers which comply
• TRI-STATE Outputs with EIA Standards for the electrical characteristics of
• Internal Hysteresis −140 mV (typ) balanced/unbalanced voltage digital interface circuits.
Receiver outputs are 74LS compatible, TRI-STATE
• Fast Propagation Times −19 ns (typ) structures which are forced to a high impedance state
• TTL Compatible Outputs when the appropriate output control pin reaches a
• 5V Supply logic zero condition. A PNP device buffers each
output control pin to assure minimum loading for
• Pin Compatible and Interchangeable with either logic one or logic zero inputs. In addition, each
MC3486 receiver has internal hysteresis circuitry to improve
noise margin and discourage output instability for
slowly changing input waveforms.

(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/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.
