SP3232EEY-L

Drivers, Receivers, Transceivers Overview

The MaxLinear SP3232EEY-L is a true RS-232 transceiver designed for portable and handheld applications. It features two drivers and two receivers, operating from a single 3.0V to 5.5V power supply. The device utilizes an internal charge pump requiring only four 0.1µF capacitors to generate ±5.5V levels. It supports data rates up to 235kbps under full load conditions. The component operates within a temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Complies with EIA/TIA-232-F standards using a single low-voltage power supply
• Integrates a high-efficiency charge pump to eliminate the need for external dual voltage sources
• Provides enhanced electrostatic discharge protection across driver outputs and receiver inputs
• Includes internal pull-down resistors on receiver inputs to prevent floating states

Drivers, Receivers, Transceivers Applications

• Portable and handheld computing devices such as notebooks and palmtops
• Battery-powered systems requiring efficient power management
• Mixed voltage environments connecting 3.3V logic to RS-232 peripherals
• Industrial control systems exposed to static discharge risks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature rating. Ensure that the procurement channel provides genuine components with traceable origin. Cross-reference the part number with the latest datasheet revision to confirm pinout compatibility and electrical specifications before finalizing orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require RS-232 communication without generating negative voltages externally. It is suitable for space-constrained designs due to the minimal external capacitor requirement. Consider the 16-pin TSSOP footprint for surface mount assembly. Verify that the system's logic levels are compatible with the TTL/CMOS inputs and outputs provided by the transceiver.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3232E series, which includes variants with different packaging options such as SSOP, NSOIC, and WSOIC. The 'EEY' suffix specifically denotes the industrial temperature range and the TSSOP package configuration. Other series members may offer shutdown modes or different pin counts depending on the specific application requirements.

Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include other SP3232E series variants like SP3232ECY-L or SP3232EEN-L, provided the package and temperature range match the design constraints. Ensure any replacement maintains the same 2-driver/2-receiver configuration and charge pump architecture.
