SP233ACT-L

Drivers, Receivers, Transceivers Overview

The SP233ACT-L/TR is an RS-232 transceiver manufactured by MaxLinear, Inc., housed in a 20-pin SOIC package. It supports full-duplex communication with two drivers and two receivers at data rates up to 120 kb/s. The device operates on a single 5V supply (4.5V to 5.5V) with a typical quiescent current of 10 mA. Key electrical parameters include 18 mA output current, 2 kV ESD protection, and propagation delays of 1.5 µs for drivers and 0.1 µs for receivers. Power dissipation is rated at 375 mW, and it functions within a commercial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Complies with RS-232F and ITU V.28 specifications
• Operates using only 0.1 µF ceramic capacitors without external charge pumps
• Provides high data rate performance under load conditions
• Includes +/-2 kV human body model ESD protection

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring serial communication
• Modem interface circuits
• Point-to-point data transmission links
• Computer peripheral connections

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official documentation to confirm lead-free compliance and RoHS status. Confirm the package variant matches the required 20-SOIC footprint. Check for moisture sensitivity level requirements during storage and handling. Ensure the component source is authorized to avoid counterfeit risks.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a standard RS-232 interface is needed with minimal external passive components. It is suitable for applications requiring full-duplex operation with moderate data rates. Consider the 20-pin package size relative to available board space. Verify that the 5V supply voltage aligns with the system power architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP233A series of enhanced RS-232 line drivers and receivers originally developed by Exar Corporation and now managed by MaxLinear. The series is designed for low-power CMOS operation while maintaining compatibility with legacy RS-232 standards. It serves as a direct replacement for older discrete solutions or competing ICs in serial communication designs.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives may include the SP233ACT from other manufacturers such as Sipex or Exar. Verify electrical characteristics like output current and ESD ratings before substitution. Ensure the replacement supports the same 20-SOIC package and operating temperature range.
