description/ordering information

The SN75ALS181 is a differential driver and receiver pair designed for bidirectional data communication on

multipoint bus transmission lines. The design provides for balanced transmission lines and meets

TIA/EIA-422-B and TIA/EIA-485-A, and CCITT recommendations V.10, V.11, X.26, and X.27.

The SN75ALS181 combines a 3-state differential line driver and a differential-input line receiver that 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 to separate pins for greater flexibility and are designed to offer

minimum loading to the bus when the driver is disabled or V

negative common-mode voltage changes, making the device suitable for party-line applications.
