3 Description

The SN65ALS1176 differential bus transceiver is

designed for bidirectional data communication on

multipoint bus transmission lines. The device is

designed for balanced transmission lines and

meets TIA/EIA-422-B, TIA/EIA-485-A, and ITU

Recommendations V.11 and X.27.

The SN65ALS1176 combines 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 an

excellent choice for party-line applications.

The SN65ALS1176 is characterized for operation from

– 25°C to 85°C.
