MAX3467CPA+

The MAX3467CPA+ is a +5V, fail-safe, profibus RS485/RS422 transceiver in 8 pin DIP package. This high speed and full 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. The MAX3467 contains one three state differential line driver and one differential input line receiver. The device 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 0°C to 70°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)
• Low supply current of 2.5mA
• Current limiting and thermal shutdown for driver overload protection
