High-ESD Profibus RS-485 Transceiver
MAX14770E
General Description
The MAX14770E is a half-duplex, Q35kV high ESD-
protected transceiver for PROFIBUS-DP and RS-485
applications. In addition, it can be used for RS-422/V.11
communications. The MAX14770E is designed to meet
IEC 61158-2, TIA/EIA-422-B, TIA/EIA-485-A, V.11, and
X.27 standards.
The MAX14770E operates from a +5V supply and has
true fail-safe circuitry that guarantees a logic-high receiv-
er output when the receiver inputs are open or shorted.
The MAX14770E features a 1/4 standard-unit load
receiver input impedance, allowing up to 128 1/4 unit
load transceivers on the bus. Drivers are short-circuit
current limited and are protected against excessive
power dissipation by thermal-shutdown circuitry.
The MAX14770E is available in an 8-pin SO and an 8-pin
F
MAX specified over the extended temperature range.
It is also available in a tiny TDFN (3mm x 3mm) package
and specified over the automotive (-40NC to +125NC) tem-
perature range.
