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.
