Product details

1 Mbps full-duplex RS-232 link in a 16-SSOP

The MAX3227IDBR is a single-channel RS-232 transceiver from Texas Instruments that pushes 1 Mbps over a full-duplex serial link — both the driver and receiver stay live simultaneously, so it handles bidirectional data without a half-duplex turnaround delay. The 500 mV of receiver hysteresis filters out noise picked up on long cable runs — a practical margin for RS-232 links that snake across a machine or between panels.

Package and board-fit — 16-SSOP footprint

The supplier device package is listed as 16-SSOP, so the same footprint serves both the package / case and the TI ordering code suffix.

Frequently asked questions

Can MAX3227IDBR replace SN65HVD233MDREP on the same board?

No — the SN65HVD233MDREP is a CANbus transceiver (half-duplex, protocol-specific), while the MAX3227IDBR is an RS-232 full-duplex part. They are not pin-compatible or protocol-compatible; a board designed for the CAN part would need a different transceiver and a different physical-layer interface.
