description
The SN65ALS176 and SN75ALS176 series differential bus transceivers are designed for bidirectional data
communication on multipoint bus transmission lines. They are designed for balanced transmission lines and
meet TIA/EIA-422-B, TIA/EIA-485-A, and ITU Recommendations V.11 and X.27.
The SN65ALS176 and SN75ALS176 series combine a 3-state, differential line driver and a differential input line
receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and
active-low enables, respectively, that can be connected together externally to function as a direction control.
The driver differential outputs and the receiver differential inputs are connected internally to form a differential
input/output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or
VCC = 0. This port features wide positive and negative common-mode voltage ranges, making the device
suitable for party-line applications.
The SN65ALS176 is characterized for operation from –40°C to 85°C. The SN75ALS176 series is characterized
for operation from 0°C to 70°C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
These devices meet or exceed the requirements of TIA/EIA-485-A, except for the Generator Contention Test (para. 3.4.2) and the Generator
Current Limit (para. 3.4.3). The applied test voltage ranges are –6 V to 8 V for the SN75ALS176, SN75ALS176A, and SN75ALS176B and
–4 V to 8 V for the SN65ALS180.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.

This is the maximum range that the driver or receiver delay times vary over
temperature, VCC, and process (device to device).
The D package is available taped and reeled. Add the suffix R to the device
type (e.g., SN75ALS176DR).
