SP3232ECY-L/TR

Drivers, Receivers, Transceivers Overview

The SP3232ECY-L/TR is a MaxLinear RS-232 transceiver in a 16-pin TSSOP package. It operates from a single 3.0V to 5.5V supply and includes two drivers and two receivers for full-duplex communication. The device meets EIA/TIA-232-F standards with a minimum data rate of 120kbps under full load, supporting up to 235kbps. It features an internal charge pump requiring four 0.1µF capacitors. The component provides enhanced ESD protection rated at ±15kV (HBM) and ±15kV air discharge. Operating temperature range is 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a high-efficiency on-board charge pump to generate true RS-232 voltage levels from a single low-voltage power supply.
• Provides robust electrostatic discharge tolerance exceeding ±15kV across driver outputs and receiver inputs using ruggedized ESD cells.
• Features built-in input hysteresis on receivers to ensure signal integrity and immunity against noise on transmission lines.

Drivers, Receivers, Transceivers Applications

• Portable and handheld computing devices such as notebook or palmtop computers
• Battery-powered systems requiring low-power serial communication interfaces
• Mixed voltage environments connecting 3.3V logic to standard RS-232 peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CY' corresponds to the 16-pin TSSOP package and the commercial temperature range of 0°C to +70°C. Confirm that the '/L/TR' designation indicates lead-free compliance and reel packaging. Cross-reference the manufacturer's current ordering information to ensure the part number remains active and matches the required pinout configuration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-pin surface-mount solution is required for portable applications. It is suitable for designs needing two independent channels without a shutdown control feature. Ensure the application can accommodate the four external 0.1µF capacitors necessary for the charge pump operation within the specified voltage range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3232E series, which consists of 2-driver/2-receiver RS-232 transceivers. Unlike the SP3222E variant, it lacks a shutdown mode. The family utilizes proprietary charge pump technology to deliver true RS-232 performance from standard logic supply voltages, targeting space-constrained mobile electronics.

Drivers, Receivers, Transceivers Replacement Considerations

SP3232EEY-L/TR: Identical electrical specifications but rated for -40°C to +85°C industrial temperature range.
