Product details

Active lifecycle — no end-of-line risk

The MAX3227IDB: For new designs, this means no last-time-buy pressure and no forced migration to a replacement. The supply chain is stable through authorized distribution, and the part can be quoted to order against any BOM quantity.

1 Mbps RS-232 link with wide supply range

The MAX3227IDB is a single-channel full-duplex RS-232 transceiver delivering 1 Mbps data rate over a single supply rail of 3V to 5.5V. The 1/1 driver/receiver count handles one transmit and one receive line — enough for a point-to-point serial port or a debug console. The 500 mV receiver hysteresis provides noise margin on longer cable runs, which matters when the RS-232 line runs through a factory floor or between cabinets. Because the supply range includes 3.3V natively, the transceiver can interface directly with a 3.3V UART on a microcontroller without an external level translator — the VCC pin simply connects to the same 3.3V rail.

16-SSOP package — board-fit note

The 16-SSOP package (0.209", 5.30 mm width) is a narrow-body surface-mount footprint common across many TI RS-232 parts. The tube packaging is typical for prototype quantities; production volumes may ship in tape-and-reel under a different order code.

Frequently asked questions

What is the data rate of MAX3227IDB?

The MAX3227IDB supports a data rate of 1 Mbps, which is sufficient for standard RS-232 applications such as industrial serial ports, terminal servers, and debug consoles.

Can MAX3227IDB be used with a 3.3V supply?

Yes, the MAX3227IDB operates from 3V to 5.5V, so a 3.3V rail is within the specified range. No external level shifter is needed when connecting to a 3.3V UART.

What package does MAX3227IDB come in?

The MAX3227IDB is supplied in a 16-SSOP package (0.209", 5.30 mm width) in tube packaging. The supplier device package is 16-SSOP.
