SP211BCT-L/TR

Drivers, Receivers, Transceivers Overview

The SP211BCT-L/TR is a high-speed RS-232 transceiver manufactured by Sipex, belonging to the SP200 series. It integrates three drivers and five receivers in a single CMOS package. The device utilizes an internal charge pump circuit to generate ±10V RS-232 voltage levels from a single +5V supply, requiring only 0.1µF external capacitors. It supports data rates up to 120kbps and includes a low-power shutdown mode that reduces supply current to 1µA with a WakeUp feature. The component meets all RS-232 and V.28 specifications and offers improved driver output capacity for mouse applications.

Drivers, Receivers, Transceivers Feature Summary

• Integrates patented on-board charge pump circuitry to eliminate the need for external voltage generators
• Features a low-power shutdown mode with active receiver wake-up capability to minimize standby power consumption
• Provides tri-state receiver outputs and enhanced driver output capacity suitable for specific peripheral connections

Drivers, Receivers, Transceivers Applications

• Industrial communication systems requiring RS-232 connectivity
• Portable equipment utilizing single +5V power supplies
• Mouse applications benefiting from improved driver output capacity

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation, as the SP200 series was originally developed by Sipex Corporation and later acquired by Exar Corporation, which is now part of MaxLinear. Confirm that the suffix 'L' indicates lead-free compliance and 'TR' denotes tape-and-reel packaging. Ensure the datasheet corresponds to the specific functional configuration of three drivers and five receivers.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple transmit and receive channels within a single IC footprint. It is appropriate for applications constrained by board space due to the use of small 0.1µF charge pump capacitors. Consider the 120kbps data rate limit and the requirement for a single +5V supply rail during system architecture planning.

Drivers, Receivers, Transceivers Part Context

The SP211BCT-L/TR is part of the broader SP200 series of multi-channel RS-232 line transceivers. This family includes various configurations such as the SP200, SP205, SP206, SP207B, SP211, and SP213 models. These devices share common technologies including low-power CMOS construction and patented charge pump circuits designed to simplify interface design and reduce overall circuit costs.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other members of the SP200 series such as the SP211 or SP207B, provided the pinout and channel count match the design requirements. Cross-reference with Exar or MaxLinear equivalents if sourcing from different distributors, ensuring electrical parameters like data rate and ESD protection remain compatible.
