RS-485 и RS-422 MAX3442EESA+

Полудуплексный RS485 приемопередатчик 250Кб/с , 4.75В-5.25В питание, SOIC-8

The MAX3442EESA+ is a fault-protected RS-485 and J1708 Transceiver feature ±60V protection from signal faults on communication bus lines. Each device contains one differential line driver with three-state output and one differential line receiver with three-state input. The 1/4-unit-load receiver input impedance allows up to 128 transceivers on a single bus. The devices operate from a 5V supply at data rates of up to 10Mbps. True fail-safe inputs guarantee a logic-high receiver output when the receiver inputs are open, shorted or connected to an idle data line. Hot-swap circuitry eliminates false transitions on the data bus during circuit initialization or connection to a live backplane. Short-circuit current-limiting and thermal shutdown circuitry protect the driver against excessive power dissipation and on-chip ±15kV ESD protection eliminates costly external protection devices.

• True fail-safe receiver inputs
• Enhanced slew-rate limiting facilitates error-free data transmission
• Allow up to 128 transceivers on the bus
