Press Release Summary:
Supplied in 6 x 6 mm, 40-pin QFN package, XR34350 features Â±10 V RS-232 driver output for diverse connectivity.Â Integrated cable terminationÂ andÂ 4 configuration modes allow all 3 protocols to be used interchangeably overÂ one cable or connector without any additional switching components. RS-232 mode (1 Mbps) provides 3 drivers and 5 receivers to support all 8 signals required for DB9 serial port (3TX/5RX), while 20 Mbps RS-485/422 modes include both half and full duplex (1TX/1RX).
Original Press Release:
Multiprotocol Transceiver Simplifies Industrial Designs & Supports Legacy Peripherals
- Supports broader range of RS-232 peripherals with wide ±10V RS-232 driver output
- Reduces component count and saves board space as a result of integrated cable termination
- Supports full DB9 RS-232 or RS-485/RS-422 serial protocols from one IC
FREMONT, Calif. -- Exar Corporation (NYSE: EXAR), a leading supplier of analog mixed-signal products serving the industrial, high-end consumer and infrastructure markets, expanded its family of single-chip RS-232/RS-485/RS-422 serial transceivers by adding the XR34350. The XR34350 features a wide ±10V RS-232 driver output that supports a wider range of RS-232 peripherals. Similar to the industry leading SP339, the XR34350 includes integrated cable termination and four configuration modes that allow all three protocols to be used interchangeably over a single cable or connector with no additional switching components. The RS-232 mode provides three drivers and five receivers to support all eight signals required for the DB9 serial port (3TX/5RX), while RS-485/422 modes include both half and full duplex (1TX/1RX).
The XR34350 operates from either a 3.3V or 5V supply, consumes only 2mA typical supply current, and offers a shutdown mode for low power (10µA) standby operation. The high speed drivers operate up to 20Mbps in RS-485/422 modes, and up to 1Mbps in RS-232 mode. All drivers can be slew limited to 250kbps in any mode to minimize electromagnetic interference (EMI).
"The XR34350 simplifies customer designs," said Dale Wedel, VP of high performance analog at Exar. "The wide driver output swing allows improved interoperability with older model bar code scanners, PS2 keyboards/mice, and other RS-232 peripherals."
All bus pins are protected against severe ESD events up to ±15kV HBM (Human Body Model), ±15kV IEC-61000-4-2 Air Gap, and ±8kV IEC 61000-4-2 Contact Discharge.
The XR34350 is available now in a RoHS compliant, green/halogen free, space-saving 6mm x 6mm, 40-pin QFN package. Pricing starts at $5.40 in quantities of 1,000. For more information, visit www.exar.com/products/interface/serial-transceivers/multiprotocol/dual-protocol.
