DS16F95, DS36F95
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 minimiz-
ing gate delay times. Thus, the DS16F95 and DS36F95 con-
sume less power, and feature an extended temperature
range as well as improved specifications.
The DS16F95/DS36F95 combines a TRI-STATE® differen-
tial line driver and a differential input line receiver, both of
which operate from a single 5.0V power supply. The driver
and receiver have an active Enable that can be externally
connected to function as a direction control. The driver differ-
ential outputs and the receiver differential inputs are inter-
nally connected 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 VCC = 0V. These
ports feature wide positive and negative common mode volt-
age ranges, making the device suitable for multipoint appli-
cations in noisy environments.
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.
The DS16F95/DS36F95 can be used in transmission line
applications employing the DS96F172 and the DS96F174
quad differential line drivers and the DS96F173 and
DS96F175 quad differential line receivers.
