SP232ACT-L/TR

Drivers, Receivers, Transceivers Overview

The SP232ACT-L/TR is a MaxLinear RS-232 transceiver IC designed for CMOS/TTL to RS-232 signal conversion. It features two drivers and two receivers, supporting full-duplex communication with a data rate of 240 kbps. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It is housed in a 16-SOIC package (0.295" width) and supports surface mount installation. The component functions within an operating temperature range of 0°C to 70°C and includes a receiver hysteresis of 500 mV. It complies with RoHS standards and has a Moisture Sensitivity Level (MSL) of 3.

Drivers, Receivers, Transceivers Feature Summary

• Integrates two independent drivers and two receivers for full-duplex RS-232 communication
• Utilizes internal charge pump circuitry to generate required RS-232 voltages from a single power supply
• Provides enhanced electrostatic discharge protection capabilities
• Supports standard CMOS/TTL logic levels at the interface

Drivers, Receivers, Transceivers Applications

• RS-232 serial port implementations in computing equipment
• Industrial control systems requiring reliable serial communication
• Embedded devices interfacing with legacy RS-232 peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ACT' against the manufacturer's current datasheet to confirm the commercial temperature grade and pinout configuration. Ensure the ordering quantity aligns with the manufacturer's standard packaging specifications, such as cut tape or reel quantities, to avoid fulfillment delays. Cross-reference the Mouser or DigiKey part numbers with the official MaxLinear documentation to validate authenticity and revision status before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-driver, dual-receiver RS-232 solution is required for single-supply applications. The 240 kbps data rate suits standard asynchronous serial links. Verify that the system environment remains within the 0°C to 70°C operational range. Confirm that the 16-SOIC footprint matches the PCB layout constraints. Consider ESD protection requirements if the interface is exposed to external connectors.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MaxLinear SP232 series, which provides low-power RS-232 transceivers. The series is characterized by its ability to operate from a single 5V supply while delivering true RS-232 performance. The SP232ACT variant specifically denotes the commercial temperature range and SOIC package option within this broader family of interface controllers.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers include ADM202JRWZ, ADM232AARWZ, and LT1081CSW#PBF. These alternatives offer similar RS-232 functionality but may differ in package type, exact electrical parameters, or pin configurations. Verify compatibility with existing circuit designs before substitution.
