Series Information for MAX3430CSA+T - Maxim Integrated


RS422/RS485 TXRX 250KBPS 3.63V NSOIC
The MAX3430 fault-protected RS-485 transceiver features ±80V protection from overvoltage signal faults on commu- nication bus lines. Each device contains one driver and one receiver, and the output pins can withstand faults, with respect to ground, of up to ±80V. Even if the faults occur when the transceiver is active, shut down, or pow- ered off, the device will not be damaged. The MAX3430 operates from a 3.3V supply and features a slew-rate-lim- ited driver that minimizes EMI and reduces reflections caused by improperly terminated cables, allowing error- free data transmission at data rates up to 250kbps. The MAX3430 has a 1/4-unit-load receiver input impedance allowing up to 128 transceivers on a single bus and fea- tures fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open. Hot-swap circuitry eliminates false transitions on the data cable during circuit initialization or connection to a live backplane. Short-circuit current limiting and ther- mal-shutdown circuitry protect the driver against exces- sive power dissipation. The MAX3430 is available in 8-pin SO and 8-pin PDIP packages, and is specified over commercial and indus- trial temperature ranges.
