DS16F95QML
EIA-485/EIA-422A Differential Bus Transceiver
General Description
The DS16F95 Differential Bus Transceiver is a monolithic
integrated circuit designed for bidirectional data communica-
tion on balanced multipoint bus transmission lines. The
transceiver meets EIA standard RS-485 as well as RS-422A.
The DS16F95 offers improved performance due to the use
of state-of-the-art L-FAST bipolar technology. The L-FAST
technology allows for higher speeds and lower currents by
utilizing extremely short gate delay times. Thus, the
DS16F95QML features lower power, extended temperature
range and improved specifications.
The DS16F95 combines a TRI-STATE® 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 con-
trol. The driver differential outputs and the receiver differen-
tial inputs are internally 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 voltage ranges, making the device suitable
for multipoint applications 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 can be used in transmission line applications
employing the DS96F172 and the DS96F174 quad differen-
tial line drivers and the DS96F173 and DS96F175 quad
differential line receivers.
