DS16F95QML
EIA-485/EIA-422A Differential Bus Transceiver
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.
General Description
The DS16F95 Differential Bus Transceiver is a monolithic in-
tegrated circuit designed for bidirectional data communication
on balanced multipoint bus transmission lines. The transceiv-
er meets EIA standard RS-485 as well as RS-422A.
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 dif-
ferential line receivers.
The DS16F95 offers improved performance due to the use of
state-of-the-art L-FAST bipolar technology. The L-FAST tech-
nology allows for higher speeds and lower currents by utilizing
extremely short gate delay times. Thus, the DS16F95QML
features lower power, extended temperature range and im-
proved specifications.
The DS16F95 combines a TRI-STATE® differential 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 differential outputs and the
receiver differential 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 dis-
abled or when VCC = 0V. These ports feature wide positive
and negative common mode voltage ranges, making the de-
vice suitable for multipoint applications in noisy environments.

Note 2: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation.
Note 3: Above TA = 25°C, derate E package 12.1mW°C, J package 8.5 mW/°C, W & WG package 4.8mW/°C.
Note 4: Human body model, 1.5kΩ in series with 100pF
Note 5: Δ|VOD| and Δ|VOC| are the changes in magnitude of VOD and VOC, respectively, that occur when the input is changed from a high level to a low level.
Note 6: Negative sign of the limits indicates the direction of the current flow only.
Note 7: RIN is guaranteed by testing “Line Input Current” (II).
Note 8: Testing at 20pF assures conformance to spec at 5pF.
Note 9: tTD = Non-inverting output rise time + inverting output fall time / 2, Non-inverting output fall time + inverting output rise time / 2.
Note 10: Rise time 20% to 80%, Fall time 80% to 20%.
Note 11: Pre and post irradiation limits are identical to those listed under A C and DC electrical characteristics. These parts may be dose rate sensitive in a space
environment and demonstrate enhanced low dose rate effect. Radiation end point limits for the noted parameters are guaranteed only for the conditions as
specified in MIL-STD 883, Method 1019, condition A.
