6-Channel, Digital Ground-Level Translator

General Description

Features

S Supports Ground Differences Up to 72V

The MAX14842 translates digital signals between two

domains that have different ground references of up to

72V. The device features six communication channels,

two bidirectional and four unidirectional. Two of the four

unidirectional channels go in each direction. The device

is powered by two supply voltages that independently

define the logic levels of each ground domain.

S Four Unidirectional Channels: Two In/Two Out

S Two Bidirectional Channels

S I C Compatible

S Supports I C Clock Stretching

S 30Mbps Unidirectional Data Rates

S 2Mbps Bidirectional Data Rates

S +3.3V to +5V Level Translation

S Undervoltage Lockout

The MAX14842 supports guaranteed data rates up to

30Mbps on the four unidirectional channels and up to

2Mbps on the two bidirectional channels. The bidirec-

tional channels have open-drain outputs, making them

suitable for I C signals. I C clock stretching and hot

swapping is supported on the bidirectional channels.

S 4mm x 4mm, 16-Pin TQFN Package

S -40NC to +125NC Automotive Temperature Range

Undervoltage lockout ensures that the output pins have

a defined behavior during power-up, power-down, and

during supply transients. For proper operation, ensure

be greater than or equal to GNDA.

Battery Management

The MAX14842 is available in a 16-pin TQFN package

and is specified over the -40NC to +125NC automotive

temperature range.
