DS16F95, DS36F95

EIA-485/EIA-422A Differential Bus Transceiver

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.

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.

Features

n Meets EIA-485 and EIA-422A

n Meets SCSI-1 (5 MHZ) specifications

n Designed for multipoint transmission

n Wide positive and negative input/output bus voltage

ranges

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.

n Thermal shutdown protection

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 V_CC= 0V. These

ports feature wide positive and negative common mode volt-

age ranges, making the device suitable for multipoint appli-

cations in noisy environments.

n Driver positive and negative current-limiting

n High impedance receiver input

n Receiver input hysteresis of 50 mV typical

n Operates from single 5.0V supply

n Reduced power consumption

n Pin compatible with DS3695 and SN75176A

n Military temperature range available

n Qualified for MIL-STD 883C

n Standard Military Drawings (SMD) available

n Available in DIP (J), SOIC (M), LCC (E), and Flatpak

(W) packages

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.
