Overview
19-3038; Rev 3; 5/12 MAX3465–MAX3469 +5V, Fail-Safe, 40Mbps, Profibus RS-485/ RS-422 Transceivers General Description The MAX3465–MAX3469 are high-speed differential bus transceivers for RS-485 and RS-422 communications.
They are designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.
11, and X.
27 standards.
The transceiver complies with the Profibus specification providing +2.
1V minimum output level with a 54Ω 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 dela...
