MAX14850

Six-Channel Digital Isolator

General Description

Benefits and Features

The MAX14850 is a six-channel digital isolator utilizing

Maxim’s proprietary process technology, whose mono-

lithic design provides a compact and low-cost transfer

of digital signals between circuits with different power

domains. The technology enables low power consumption

and stable high-temperature performance.

S Protection from High-Voltage Environments

 600V

Isolation for 60 Seconds

RMS

 Short-Circuit Protection on Unidirectional

Outputs

S Complete Digital Isolation Solution

 Four Unidirectional Signal Paths: 2-In/2-Out

 Two Bidirectional Open-Drain Signal Paths

 50Mbps (max) Unidirectional Data Rate

 2Mbps (max) Bidirectional Data Rate

The four unidirectional channels are each capable of

DC to 50Mbps, with two of the four channels passing

data across the isolation barrier in each direction. The

two bidirectional channels are open drain and each is

capable of data rates from DC to 2Mbps.

S Compatible with Many Interface Standards

 I²C With Clock Stretching

 SPI

Independent 3.0V to 5.5V supplies on each side of the

isolator also make it suitable for use as a level translator.

The MAX14850 can be used for isolating SPI busses, I²C

busses with clock stretching, RS-232, RS-485/RS-422

busses, and general-purpose isolation. When used as

a bus isolator, extra channels are available for power

monitoring and reset signals.

 RS-232, RS-422/RS-485

 SMBus, PMBus Interfaces

Ordering Information appears at end of data sheet.

The MAX14850 is available in a narrow body,16-pin SO

(10mm x 4mm) package. The SO package is specified

over the -40NC to +125NC automotive temperature range.
