Sipex Corp. has introduced three RS485 transceivers with data rates of 20Mbps, 15kV ESD protection, low power operation, and industry standard form factors.

Suitable for RS485 and RS422 applications such as security systems, instrumentation, data-com, and point of sale networks, the SP1481E, SP1490E and SP1491E transceivers feature an open-receiver failsafe state, single 5V power supply operation, differential driver output of at least 1.5V into RS485 loads or 2V into RS422 loads, no-load supply current of 900?A, and receiver input impedance of up to 32 single unit-load receivers per bus segment.

The SP1481E is a half-duplex transceiver while the SP1490E and SP1491E are full-duplex and can be used to create repeaters to extend the reach of a differential bus. Both the SP1481E and SP1491E offer low power shutdown.

The SP1481E and SP1490E are housed in 8-pin NSOIC and 8-pin PDIP, while the SP1491E is offered in 14-pin NSOIC and 14-pin PDIP packages. Available in both commercial and extended temperature ranges, the products have prices starting at $1.75 for 1,000-piece quantities.
