EIA-485/EIA-422A Differential Bus Transceiver
General Description
The DS16F95/DS36F95 Differential Bus Transceiver is a
monolithic integrated circuit designed for bidirectional data
communication on balanced multipoint bus transmission
lines. The transceiver meets both EIA-485 and EIA-422A
standards.
The DS16F95/DS36F95 offers improved performance due to
the use of L-FAST bipolar technology. The L-FAST technol-
ogy allows for higher speeds and lower currents by minimizing
gate delay times. Thus, the DS16F95 and DS36F95 consume
less power, and feature an extended temperature range as
well as improved specifications.
The DS16F95/DS36F95 combines a TRI-STATE
line driver and a differential input line receiver, both of which
operate from a single 5.0V power supply. The driver and re-
ceiver have an active Enable that can be externally connected
to function as a direction control. The driver differential out-
puts and the receiver differential inputs are internally con-
nected to form differential input/output (I/O) bus ports that are
designed to offer minimum loading to the bus whenever the
driver is disabled or when V
positive and negative common mode voltage ranges, making
the device suitable for multipoint applications in noisy envi-
ronments.
The driver is designed to accommodate loads of up to 60 mA
of sink or source current and features positive and negative
current limiting in addition to thermal shutdown for protection
from line fault conditions.
