MaxLinear, Inc. Drivers, Receivers, Transceivers SP337EUET-L

The SP337EUET-L is a dual mode serial transceiver from Quarktwin Technology Ltd. that supports both RS-232 and RS-485/422 communication protocols. In RS-232 mode, it features three drivers and five receivers, accommodating all eight signals typically found in a DB9 serial port connector, with a maximum data rate of 1Mbps. In RS-485 mode, it provides two independent transmit and receive channels, capable of achieving data rates up to 15Mbps. The device operates with a single power supply ranging from 3.3V to 5V and utilizes high-efficiency charge pumps to deliver RS-232 driver output voltages. It includes advanced failsafe protection for RS-485 receivers to prevent oscillation when inputs are unconnected, and all driver outputs and receiver inputs are protected against ESD strikes up to ±15,000 volts. The SP337EUET-L is packaged in a 28-pin TSSOP format, making it suitable for various applications including industrial computers, process control equipment, and networking devices.
