Isolated RS-485 Half-Duplex Evaluation Module
This user's guide describes the evaluation module (EVM) for a RS-485 half-duplex transceiver. This EVM
helps designers evaluate the device performance for fast development and analysis of data transmission
systems using any of the TI RS-485 half-duplex devices in a 16-pin DW package.
CAUTION
Do not use this EVM for isolation voltage tests even though the half-duplex
device has galvanic isolation of up to 4000 V. This EVM is designed for the
evaluation of device operating parameters only. If a high voltage (greater than
5.5 V) is applied anywhere in the circuit, the EVM could be damaged.

Introduction

Introduction
The ISO141x family of devices is an isolated differential line transceiver for TIA/EIA 485/422 applications.
The devices with the B suffix are 5-kVRMS, basic isolated transceivers. The basic isolation devices can be
used for long transmission lines because the ground loop is broken. The broken ground loop lets a much
larger range of common-mode voltage be used in the design.
The symmetrical isolation barrier of the device is tested to give 5000 VRMS of isolation for 60 s per UL 1577
between the bus-line transceiver and the logic-level interface. Any cabled I/O can have electrical noise
transients from various sources. These noise transients can cause damage to the transceiver, nearby
sensitive circuitry, or both if the transients are of sufficient magnitude and duration. These isolated devices
can significantly increase protection and decrease the risk of damage to expensive control circuits. The
bus pins can endure high levels of IEC ESD and EFT events. No additional components for system-level
protection are needed because of this endurance.
This EVM can evaluate different system parameters of the devices. Test signals and sequences can be
applied to the device and different performance characteristics such as propagation delay, power
consumption, and different bus and driver conditions. Users can evaluate these parameters in their own
lab environment.
The EVM has footprints named DNI for additional components that are not needed to test the standard
functionality. Add components to these footprints for evaluation and to get specific system requirements.
Refer to this users guide for the basic functionality that can be assessed with the EVM.
Go to the isolated RS-485 transceiver page on TI.com for data sheets and a detailed description of the
ISO141x devices. Review the TI E2E™ Online Community for digital isolators to find technical support for
this EVM and other isolated devices. This EVM is designed with the signal paths for the half-duplex
operation.

Part Number
The 50-Ω resistors R3, R5, and R6, have the index n.a., indicating that these components are not assembled. Because signal
generators have a typical source impedance of 50 Ω, their output signal is twice the required signal voltage and assumes that
the on board 50-Ω resistors divide this voltage down to the correct signal level.
J3 and J4 can only be used when these resistors are not populated.

EVM Setup and Operation
Figure 6 shows the basic setup of the EVM with two power supplies needed to evaluate isolator
performance. Use voltages that are within the range given in the device data sheet. The typical voltages
for the VCC1 and VCC2 supplies are 3.3 V and 5 V. Separate power supplies generate each supply voltage.
The supply voltages do not need to have the same value. If both side are to be evaluated at the same
supply voltage, only one power supply is required. This one power supply can power both sides of the
EVM.
