MaxLinear, Inc. Interface - Interface - Drivers, Receivers, Transceivers - SP3243ECA-L/TR SP3243ECA-L/TR

The SP3243ECA-L/TR is a 3 driver/5 receiver RS-232 transceiver designed for portable and hand-held applications, operating from a power supply range of +3.0V to +5.5V. It meets EIA/TIA-232-F standards and is interoperable with EIA/TIA-232 and EIA/TIA-562 down to +2.7V. The device features an AUTO-ONLINE® circuitry that allows it to wake from a low-power shutdown state when an RS-232 cable is connected. It utilizes a regulated charge pump that ensures stable RS-232 outputs despite variations in supply voltage, requiring only 0.1µF capacitors for operation. The SP3243ECA-L/TR supports a minimum transmission rate of 120kbps and has enhanced ESD protection with ratings of ±15kV for the Human Body Model and IEC61000-4-2 air discharge. This transceiver is suitable for high-speed RS-232 applications, making it a viable choice for engineers looking for reliable communication solutions in their designs.
