The MAX3243CPW from Maxim is a 3-driver\/5-receiver RS-232 transceiver with auto-powerdown feature that reduces supply current to 1 \u00b5A when all receivers are idle. It operates from 3.0V to 5.5V with \u00b115 kV ESD protection, targeting battery-powered and low-power serial communication.<\/p>\n

Principio de funcionamiento<\/h2>\n

Three driver channels convert CMOS\/TTL logic to \u00b15.4V RS-232 levels using internal charge pump. Five receiver channels convert RS-232 levels back to CMOS\/TTL. Auto-powerdown circuit monitors all receiver inputs; when no valid RS-232 signal is detected on any receiver, the device enters 1 \u00b5A shutdown. FORCEON input overrides auto-powerdown for immediate wake-up.<\/p>\n
