description
The SN65ALS1176 differential bus transceiver is designed for bidirectional data communication on multipoint
bus transmission lines. It 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 suitable for party-line
applications.
The SN65ALS1176 is characterized for operation from – 25°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential I/O bus voltage, are with respect to network ground terminal.
2. The package thermal impedance is calculated in accordance with JESD 51.
