Product details

RS232 transceiver with 250 kbps — what the data rate buys you

The Texas Instruments MAX232ECNG4 is a full-duplex RS232 transceiver in a 16-pin DIP package, carrying two drivers and two receivers (2/2) for bidirectional serial communication over standard RS232 voltage levels. The 250 kbps data rate covers the common UART baud rates up to 230.4 kbps with margin, so it handles legacy serial ports, industrial terminal interfaces, and debug consoles without timing pressure.

Through-hole DIP — board fit and assembly

Housed in a 16-DIP (0.300", 7.62 mm) through-hole package, the MAX232ECNG4 is designed for socketed or wave-soldered PCB assembly.

The base product number is MAX232, a long-running industry-standard RS232 interface family with broad second-source availability.

Frequently asked questions

What is the data rate of MAX232ECNG4?

The MAX232ECNG4 supports a data rate of 250 kbps, which covers standard RS232 baud rates up to 230.4 kbps with margin for typical serial communication applications.

What is the equivalent or replacement for MAX232ECNG4?

The MAX232ECNG4 is a member of the MAX232 family, which includes multiple pin-compatible variants from Texas Instruments and other manufacturers. The base MAX232 function (2/2 driver/receiver, 5 V supply, DIP package) is widely second-sourced. For a direct drop-in, any MAX232 or MAX232A variant in a 16-DIP package with the same pinout and supply range is functionally equivalent. Confirm the specific temperature grade and data rate of the alternate against your design requirements.
