MAX3464 Datasheet | Maxim Integrated

19-2217; Rev 1; 2/03 +5V, Fail-Safe, 20Mbps, Profibus RS-485/ RS-422 Transceivers General Description The MAX3460- MAX3464 are high-speed differential bus transceivers for RS-485 and RS-422 munications. They are designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11, and X.27 standards. The transceiver plies with the Profibus specification providing +2.1V output level with a 54Ω load, 20Mbps 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...
