The MAX3221 is a versatile RS-232 line driver and receiver IC from Analog Devices, suitable for a wide range of applications including industrial PCs, wired networking, and battery-powered systems.
This device operates from a single 3-V to 5.5-V supply and meets or exceeds TIA/EIA-232-F and ITU V.28 standards. It supports data signaling rates up to 250 kbps and features ±15 kV ESD protection on its bus pins.
The MAX3221 includes flexible power management options, such as an automatic power-down feature that reduces supply current to 1 μA typical when the serial port is inactive and no valid RS-232 signal is detected. It is available in SSOP and TSSOP packages.
Key electrical characteristics include a low standby current and the ability to accept 5-V logic input with a 3.3-V supply, making it adaptable to various system designs.
