Product details

RS-232 transceiver with 2/2 driver/receiver count

The MAX232ID: Full-duplex RS-232 transceiver with two drivers and two receivers — enough for a standard serial port with hardware handshaking (RTS/CTS). The 120 Kbps data rate covers the legacy 115.2 Kbps ceiling and then some; it is not a high-speed part, but it is the right fit for industrial control panels, PLC programming ports, and embedded debug UARTs where the bus runs at 9.6–115.2 Kbps. The 16-SOIC package is the standard SOIC-16 footprint; board layout is interchangeable with any other SOIC-16 RS-232 transceiver from the MAX232 family.

The 1.27 mm pitch is a standard SOIC footprint — no fine-pitch rework required. The tube packaging is the default for engineering samples and low-volume production; reel options are available through the standard order code variants.

Frequently asked questions

What compliance documentation does Texas Instruments provide for MAX232ID?

MAX232ID is RoHS3 compliant. Texas Instruments publishes the standard RoHS/REACH declaration and material composition data for the 16-SOIC package. No UL or IEC certification is listed on this part record; the compliance package covers the EU RoHS directive only.

What is MAX232ID's data rate and supply voltage?

The 5V rail is required — this part does not operate at 3.3V. The 120 Kbps ceiling is sufficient for legacy RS-232 at 115.2 Kbps; for higher-speed serial (e.g., 460 Kbps or 921.6 Kbps), a different transceiver family is needed.
