MAX3232CDBG4

Overview

The MAX3232CDBG4 is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V supply and includes two drivers and two receivers for full-duplex communication with a data rate of 250 kb/s. The device features -15-kV ESD protection on all RS-232 ports and requires only four external 0.1-µF capacitors. It is housed in a 16-pin SOIC package (DB) and supports an operating temperature range of 0°C to +70°C.

Feature Summary

Integrated charge pump circuitry requiring only four small external capacitors
-15-kV electrostatic discharge protection on transceiver inputs and outputs
Low-power design with shutdown mode reducing supply current to less than 1 µA

Applications

Portable equipment such as laptops, palmtops, and cellular phones
Modems and fax machines
Industrial control systems and portable instruments

Procurement Notes

Verify the suffix G4 indicates lead-free RoHS-compliant packaging when sourcing. Confirm the DB package designation matches the required surface-mount footprint. Ensure the C grade aligns with commercial temperature requirements rather than extended industrial ranges.

Selection Notes

Select this component for applications requiring robust ESD protection without external shielding. It is suitable for designs constrained by low power budgets due to its shutdown capability. Verify that the 250 kb/s speed meets system timing needs compared to higher-speed alternatives.

Part Context

This part belongs to the MAX3232 family of true RS-232 transceivers. It shares functional similarities with the MAX3222 but offers enhanced ESD protection ratings. The device serves as a standard interface solution for converting TTL/CMOS logic levels to RS-232 voltages.
