Maxim MAX3238 RS-232 Transceiver Datasheet
The MAX3238 is a true RS‑232 transceiver that operates from 3.0 V to 5.5 V and achieves a 1 µA supply current in AutoShutdown Plus mode. It provides a 5‑driver/3‑receiver serial port, a guaranteed 250 kbps data rate, and a dual charge‑pump power supply for true RS‑232 levels.
Key features include the AutoShutdown Plus power‑saving function, an always‑active non‑inverting receiver output (R1OUTB), flow‑through pinout, and compatibility with notebook, sub‑notebook and handheld applications. The device is offered in a space‑saving SSOP28 package and includes detailed electrical characteristics, pin descriptions, and recommended capacitor values for optimal performance.
