MAX3070EESD+

MAXIM INTEGRATED PRODUCTS  MAX3070EESD+.  收发器, RS422/RS485 驱动器, 2.97V-3.63电源, SOIC-14

The is a ±15kV ESD-protected, fail-safe, hot-swap, RS-485/RS-422 Transceiver. This device includes fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic high if all transmitters on a terminated bus are disabled high impedance. The MAX3070E include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion. The MAX3070E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX3070E is intended for full-duplex communications. The MAX3070E transceiver draw 800µA of supply current when unloaded or when fully loaded with the drivers disabled. All devices have a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus.
