General Description
The MAX3465–MAX3469 are high-speed differential
bus transceivers for RS-485 and RS-422 communica-
tions. They are designed to meet TIA/EIA-422-B,
TIA/EIA-485-A, V.11, and X.27 standards. The trans-
ceiver complies with the Profibus specification provid-
ing +2.1V minimum output level with a 54
load,
40Mbps data rate, and output skew less than 2ns. Each
part contains one three-state differential line driver and
one differential input line receiver. The devices operate
from a +5V supply and feature true fail-safe circuitry,
which guarantees a logic-high receiver output when the
receiver inputs are open or shorted. This enables all
receiver outputs on a terminated bus to output logic
highs when all transmitters are disabled.
All devices feature a 1/4-standard-unit load receiver
input impedance that allows 128 transceivers on the
bus. Driver and receiver propagation delays are guar-
anteed under 20ns for multidrop, clock distribution
applications. Drivers are short-circuit current limited
and are protected against excessive power dissipation
by thermal-shutdown circuitry. The driver and receiver
feature active-high and active-low enables, respective-
ly, that can be connected together externally to serve
as a direction control.
