Product details

RS-232 transceiver with 250 kbps throughput — what the data rate means for your serial link

It handles serial data at 250 kbps, which is the standard rate for legacy RS-232 ports on industrial controllers, point-of-sale terminals, and telecom equipment — fast enough for most UART-based communication but not suited for high-speed synchronous protocols.

5 V supply rail — not a 3.3 V part

The charge-pump circuitry inside generates the RS-232 voltage levels (±5 V to ±15 V typical) from the single 5 V input, eliminating the need for a separate ±12 V supply — a design convenience that made the MAX232 family a de facto standard for decades.

New designs should not use this part. For existing BOM lines, the only sourcing channel is the independent distribution market — surplus inventory, new-old-stock, or broker-sourced material. No stock or lead-time number can be stated here because each procurement lot is sourced individually.

Frequently asked questions

What is the replacement for MAX232ECDWRG4?

Pin-compatible replacements include the MAX232E (industrial temperature range) and the standard MAX232 (commercial temperature). For 3.3 V systems, the MAX3232 family offers the same pinout with a wider supply range. All are 2/2 driver/receiver RS-232 transceivers in the 16-SOIC package.

What is the data rate of MAX232ECDWRG4?

The data rate is 250 kbps, which is the standard rate for legacy RS-232 communication. It is suitable for most UART-based serial links but not for high-speed synchronous protocols.
