5.7 kV RMS Signal and Power Isolated

RS-485 Transceiver with 15 kV IEC ESD

ADM2867E/ADM2865E/ADM2863E/ADM2861E

Data Sheet

FEATURES

GENERAL DESCRIPTION

5.7 kV rms isolated RS-485/RS-422 transceiver

The ADM2861E, ADM2863E, ADM2865E, and ADM2867E

Low radiated emissions, integrated, isolated dc-to-dc

converter

Passes EN 55032 Class B with margin on a 2-layer PCB

Cable invert smart feature

Correct reversed cable connection on A, B, Y, and Z bus

pins while maintaining full receiver fail-safe feature

ESD protection on RS-485 A, B, Y, and Z pins

≥ 12 kV IEC61000-4-2 contact discharge

≥ 15 kV IEC61000-4-2 air discharge

High speed 25 Mbps data rate (ADM2865E/ADM2867E)

Low speed 500 kbps data rate for EMI control

(ADM2861E/ADM2863E)

are 5.7 kV rms signal and power isolated RS-485 transceivers.

These devices are designed for balanced transmission lines and

comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E).

The devices pass radiated emissions testing to the EN 55032

Class B standard with margin on a 2-layer printed circuit board

(PCB) using two small external 0402 ferrites on isolated power

and ground pins. The device features an integrated, low

electromagnetic interference (EMI), isolated dc-to-dc

converter, which eliminates the need for an external isolated

power supply. The isolation barrier provides immunity to

system level electromagnetic compatibility (EMC) standards.

The family of isolator devices features 12 kV contact and 15 kV

air IEC61000-4-2 ESD protection on the RS-485 A, B, Y, and

Z pins. The devices also features cable invert pins, allowing the user

to quickly correct reversed cable connection on the A, B, Y, and

Z bus pins while maintaining full receiver fail-safe performance.

Flexible power supplies

Input V_CCsupply of 3 V to 5.5 V

Logic V_IOsupply of 1.7 V to 5.5 V

V_SELpin to select V_ISOsupply of 5 V (V_CC> 4.5 V) or 3.3 V

PROFIBUS compliant for 5 V V_ISO

Slew rate limited versions are available, which are optimized for

low speed over long cable runs, and have a maximum data rate

of 500 kbps. Half duplex and full duplex variants are available.

The full duplex generics allow independent cable inversion of

the driver and receiver for additional flexibility.

Wide operating temperature range: −40°C to +105°C

High common-mode transient immunity: 250 kV/µs

Short-circuit, open-circuit, and floating input receiver fail-safe

Supports 192 bus nodes (72 kΩ receiver input impedance)

Full hot swap support (glitch free power-up/power-down)

Safety and regulatory approvals (pending)

Table 18 shows the summary description of each generic.

CSA Component Acceptance Notice 5A, DIN V VDE V 0884-

11, UL 1577, CQC11-471543-2012, IEC 61010-1

Complies with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E)

28-lead, fine pitch SOIC_W package (10.15 mm × 10.05 mm)

with >8.0 mm creepage and clearance

APPLICATIONS

Heating, ventilation, and air conditioning (HVAC) networks

Industrial field buses

Building automation

Utility networks

Energy meters

Rev. B
