What this RS-232 transmitter does
The MAX3190EEUT is an RS-232 transmitter from Analog Devices, designed to convert logic-level UART signals to the ±5V to ±15V swing required by RS-232 serial ports. It sits in the Sensors & Transducers category, which covers interface ICs used in industrial sensor links, legacy COM-port adapters, and data-acquisition front ends.
Package and supply format
(tube or tray), not tape-and-reel. This affects automated assembly: bulk parts require tube feeders or manual loading, and the minimum order quantity may differ from reeled parts. Confirm your pick-and-place setup can handle bulk delivery before committing the BOM line.
No official second-source or drop-in replacement listed; the MAX3190EEUT is the only order code in this series with the RS-232 transmitter function.
