Original Press Release:
Sipex Announces Low Voltage RS232 Transceiver for Portable Applications
(Milpitas, CA - June 24, 2003) - Sipex Corporation (NASDAQ:SIPX) today introduces the SP3281EB, the newest RS232 transceiver added to Sipex's Interface product family. With 5 drivers, 3 receivers and a minimum data rate of 250 Kbps, the SP3281 is ideal for cell phones, PDAs, data cables, notebooks, laptop computers and other portable applications. The device's enhanced ESD protection on all I/O pins protects the device to ±15KV using Human Body Model and ±8KV using IEC 1000-4-2 Contact Discharge.
The SP3281 operates from a single +2.35V to 5.5V supply voltage, with full RS232 compliance down to 3.1V and RS232-compatible performance down to +2.35V. Its wide supply voltage operation allows the device to be powered directly off of a Lithium-Ion battery, thus eliminating the need for a voltage regulator.
The SP3281 includes a unique pin that allows for interoperation of mixed logic voltage systems down to 1.8V. This VL pin offers power to both the input and output logic pins thus eliminating the need for external logic translators.
