3.3V/5.0V single-chip RS-232/RS-485/RS-422 serial transceiver
Exar has released single-chip RS-232/RS-485/RS-422 serial transceiver. The SP336 feature 1/8th unit load capability (up to 256 transceivers on the serial communication bus), full or half duplex configuration capability, and diagnostic loop-back function. SP336 is suggested for factory automation, process controls, embedded PCs, security networks, and point-of-sales equipment, amongst others.
"Exar continues to strengthen its leadership position in single-chip, high performance multiprotocol transceivers with the addition of the SP336," said Hensen Wong, technical marketing manager, Interface Product Line. "Building on Exar's highly successful single-chip SP33x family, the SP336's unmatched flexibility and superior ESD performance will significantly reduce component count and streamline serial port designs."
Product Features:
SP336 can be reconfigured into eight operating modes including RS-232-only (4Tx/4Rx), RS-485/RS-422-only (2Tx/2Rx) full or half duplex, two RS-232/RS-485/RS-422 mixed-modes, two shutdown modes and a diagnostic loop-back mode.. All bus-pins are protected against severe ESD events up to ±15kV (IEC 61000-4-2 air-gap) and ±8kV (IEC 61000-4-2 contact). The selectable slew rate controlled outputs minimize problems with reflections and ringing on long or un-terminated cables. When configured in RS-485/RS-422 mode, each driver may be individually enabled or tri-stated, simplifying use on shared buses or bidirectional communication. Products are available in Commercial (0 to +70șC) and Industrial (-40 to +85șC) operating temperature ranges.
