MAX3318ECUP+

MAX3318ECUP+ is a 2.5V powered RS-232 compatible transceiver. This device features AutoShutdown Plus™, and enhanced electrostatic discharge (ESD) protection integrated into the chip. It achieves a 1µA supply current using Analog Device's revolutionary auto shutdown plus feature. This device automatically enters a low-power shutdown mode when the RS-232 cable is disconnected or the transmitters of the connected peripherals are inactive for more than 30 seconds. They turn on again when they sense a valid transition at any transmitter or receiver input. It is used in applications such as palmtop computers, hand-held instruments, pagers, cellular phones, GPS, handy terminals, hand-held electronic books.
