DESCRIPTION
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 VCC = 0. These ports
feature wide positive and negative common-mode
voltage changes, making the device suitable for
party-line applications.
