Frequently Asked Questions
What supply voltage does the MAX232DW require?
The MAX232DW operates from a single 5V supply. It uses an integrated charge pump with external capacitors to generate the ±10V voltages required by the RS-232 standard internally, eliminating the need for a separate dual power supply.
How many RS-232 channels does the MAX232DW support?
The MAX232DW supports 2 transmitter (driver) channels and 2 receiver channels, making it a dual RS-232 transceiver. This is ideal for full-duplex serial communication with devices like PCs, modems, and other RS-232 equipment.
What package is the MAX232DW available in, and are there alternatives?
The MAX232DW comes in a 16-pin SOIC (Small Outline IC) package. Texas Instruments also offers the MAX232D in a 16-pin PDIP package for through-hole designs, and the MAX3232 as a lower-voltage (3.3V) alternative for modern low-power applications.
What interface standards does the MAX232DW comply with?
The MAX232DW is compliant with EIA-232-F, TIA-232-F, and V.28 interface standards. These are the industry-standard specifications for RS-232 serial communication, ensuring compatibility with a wide range of serial devices and host systems.
