MAX3468ESA+ (MAXIM INTEGRATED PRODUCTS)
Приемопередатчик RS422, RS485, 4.75В-5.25В питание, 1 драйвер, NSOIC-8
The MAX3468ESA+ 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. The MAX3468 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 -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
