产品概述

The MAX3468ESA+T from Maxim Integrated Products is a +5V, fail-safe, profibus RS485/RS422 transceiver in 8 pin NSOIC package. This high speed and half duplex differential bus transceiver is designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11 and X.27 standards. It complies with profibus specification providing +2.1V minimum output level with 54ohm load and 40Mbps data rate. It contains one 3/1 state differential line driver/receiver. It operates from +5V supply and feature true fail-safe circuitry which provides logic high receiver output when receiver inputs are open or shorted. This enables all receiver outputs on a terminated bus to output logic highs when all transmitters are disabled. It has 1/4 standard unit load receiver input impedance that allows 128 transceivers on the bus. The driver and receiver has active-high and active-low enables respectively and can be connected together externally to serve as a direction control. It is used in level translators.
  • Supply voltage range from 4.75V to 5.25V
  • Operating temperature range from -40°C to 85°C
  • 15ns transmitter propagation delay and 20ns receiver propagation delay
  • 2ns transmitter and receiver skew
  • Designed for multipoint transmissions on long or noisy bus lines
  • High differential driver output level (2.1V on 54ohm)
  • 1µA shutdown supply current and low supply current of 2.5mA
  • Current limiting and thermal shutdown for driver overload protection
  • Receiver/driver enable function, low power shutdown mode and hot swap function
  • High-Speed RS-422 Communications; High-Speed RS-485 Communications; Industrial-Control Local Area Networks; Level Translators; PROFIBUS Applications
