Product details

RS-232 link with a single supply rail

It handles serial data at 1 Mbps, which covers common baud rates up to 115200 and beyond for legacy COM ports or industrial terminal links. The supply range of 3V to 5.5V lets it run directly off a 3.3V or 5V rail without an extra regulator — a practical fit for mixed-voltage boards where the UART lives on the 3.3V side and the RS-232 bus needs 5V-compatible levels.

Housed in a 16-SSOP (0.209-inch body width, 5.30 mm), the package has a 0.65 mm lead pitch — a standard footprint that places without trouble on a two-layer board.

Frequently asked questions

Is TRS3227ECDBR a direct replacement for MAX3227?

The TRS3227ECDBR is a functional equivalent to the MAX3227 family — same 1/1 driver/receiver count, same 1 Mbps data rate, same 3V to 5.5V supply range, and same 16-SSOP footprint. Pin compatibility should be verified against the specific MAX3227 variant on your BOM before committing the board.

What is TRS3227ECDBR's listed type and duplex?

The device is a Transceiver with Full duplex operation — it can transmit and receive simultaneously on separate RS-232 lines, which is standard for a two-wire serial link.
