MAX207CDB

Drivers, Receivers, Transceivers Overview

The MAX207CDB is a full-duplex RS-232 transceiver manufactured by Texas Instruments, designed for serial communication applications. It integrates five drivers and three receivers within a single package, supporting data rates up to 120Kbps. The device operates on a single 5V supply voltage with a specified range of 4.75V to 5.25V. It utilizes internal charge pumps to generate the necessary positive and negative voltages for RS-232 signaling without requiring external components. The component is housed in a 24-pin SSOP (Shrink Small Outline Package) with a width of 5.30mm. It is rated for commercial operating temperatures ranging from 0°C to 70°C and features 500mV hysteresis on the receivers to improve noise immunity.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the datasheet to confirm package type and temperature grade. The 'C' designation typically indicates commercial temperature range. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration for your assembly process. Cross-reference manufacturer documents to confirm RoHS compliance status for current production units.

Drivers, Receivers, Transceivers Selection Notes

Select this component when five transmit channels and three receive channels are required in a compact surface-mount footprint. It is suitable for designs constrained by space where external voltage generation is undesirable. Compare pin compatibility with legacy MAX207 variants if replacing existing circuits. Verify that the 120Kbps speed meets the system's timing requirements and that the 5V logic levels align with the microcontroller interface.

Drivers, Receivers, Transceivers Part Context

The MAX207 series belongs to Texas Instruments' family of RS-232 interface integrated circuits. It serves as a high-performance alternative to older discrete solutions, offering reduced board space and simplified power design. The CDB variant specifically denotes the shrink small outline package, which provides higher pin density compared to standard SOIC packages while maintaining similar electrical characteristics to other MAX207 derivatives.
