Intersil has introduced the ISL333X family of dual protocol transceivers, designed to reduce component count and eliminate multiplexing networks, distilling as many as five different component functions into one single transceiver.
These devices can operate as one- or two-channel transceivers, as well as switch between RS232 and RS485/RS422 protocols. This adaptability enables them to potentially replace two RS232s, two RS485/RS422s and a multiplexing network.
The ICs also incorporate 15 kV (HBM) ESD protection across the full product family, which comprises the dual-port ISL3332 and ISL3333, and the single-port ISL3330 and ISL3331. The ISL3331 and ISL3333 are available in 40-pin QFN packages and all four versions operate on 3,3 V supplies, provide data rates of 20 Mbps and feature flow-through pinouts to simplify board layouts.
The ISL3331 and ISL3333 provide additional functionality, including lower speed and edge rate options for EMI (electromagnetic interference) sensitive designs, or to allow longer bus lengths. These devices also feature a logic supply voltage pin (VL) that sets the VOH level of logic outputs and the switching points of logic inputs, to be compatible with another supply voltage in mixed voltage systems.
When any port on each of the devices is in RS232 mode, an onboard charge pump generates compliant ±5 V output levels. Each transceiver is RS232 compliant with the Rx outputs handling up to ±25 V and the Tx output handling ±8 V. In RS485 mode, each transceiver supports RS485 and RS422 differential communication standards. The RS485 receiver features full failsafe operation, so the output remains high even if inputs are open or shorted. The RS485 transmitter supports as many as three data rates; two are slew-rate limited. Charge pumps are disabled when both ports on the dual port ICs are in RS485 mode, to save power, minimise noise and eliminate pump capacitors.
Applications include single board computers, factory automation systems, security networks, industrial and process control networks, point-of-sale equipment, gaming and level transistors.
