Intersil Corporation - Intersil’s Ultra-Flexible Dual Protocol Transceivers Deliver High ESD Protection in Tiny Form Factor

ISL333X Family Combines Flexibility, 15kV Human-Body Model (HBM) ESD Protection and Fast Data Rates Up To 20 Mbps in a Space-Saving 40-Pin QFN Package

MILPITAS, CA, September 5, 2008 – Intersil Corporation (NASDAQ Global Select: ISIL), a apple baton in the architecture and accomplish of high-performance analog semiconductors, today alien the ISL333X ancestors of bifold agreement transceivers. The anatomic adaptability of this ancestors is advised to abate basic calculation and annihilate multiplexing networks, abbreviation as abounding as 5 altered basic functions into one individual transceiver.

These accessories can accomplish as one or two-channel transceivers, as able-bodied as about-face amid RS-232 and RS-485/RS-422 protocols. This ability enables the ISL333X ancestors to potentially alter two RS-232s, two RS-485/RS-422s and a multiplexing network.

For the aboriginal time anytime in tiny 6mm x 6mm QFN size, this best-in-class adaptability comes with the added account of 15kV (HBM) ESD protection. This top akin of ESD aegis is accessible above the abounding ISL333XE artefact family, including the two bifold anchorage ICs, the ISL3332 and ISL3333, and the ISL3330 and ISL3331 individual anchorage ICs.

The ISL3331 and ISL3333 are accessible in ultra-small 40-pin QFN bales and all four versions accomplish on 3.3V supplies, accommodate abstracts ante of 20Mbps and affection flow-through pinouts to abridge axle layouts.

The ISL3331 and ISL3333 accommodate added functionality, including lower acceleration and bend amount options for EMI (electromagnetic interference) acute designs, or to acquiesce best bus lengths. These accessories aswell affection a argumentation accumulation voltage pin (VL) that sets the VOH akin of argumentation outputs and the switching credibility of argumentation inputs, to be accordant with addition accumulation voltage in alloyed voltage systems.

When any anchorage on anniversary of the accessories is in RS-232 mode, an on-board allegation pump generates adjustable ±5V achievement levels. Each transceiver is RS-232 adjustable with the Rx outputs administration up to ±25V and the Tx achievement administration ±8V. In RS-485 mode, anniversary transceiver supports RS-485 and RS-422 cogwheel advice standards. The RS-485 receiver appearance abounding failsafe operation so achievement charcoal top even if inputs are accessible or shorted. The RS-485 transmitter supports as abounding as three abstracts rates; two are slew-rate limited. Charge pumps are disabled if both ports on the bifold anchorage ICs are in RS-485 mode, to save power, abbreviate babble and annihilate pump capacitors.

Applications cover individual axle computers, branch automation systems, aegis networks, automated and action ascendancy networks, point-of-sale equipment, gaming, and akin transistors.

Pricing and Availability

The ISL3331 and ISL3333 are accessible in baby 40-pin QFN packages. The ISL3330 is accessible in a 20-lead SSOP and the ISL3332 is accessible in a 28-lead SSOP package.

Prices for the individual anchorage ISL3330 and ISL3331 alpha at $3.30 anniversary in 1,000-unit quantities. Pricing for the bifold anchorage ISL3332 and ISL3333 are priced at $3.90 anniversary in 1,000-unit quantities.
