MAX221ECUE+T

MAX221ECUE+T is a single RS-232 transceiver with auto shutdown. This +5V powered, single transmit/ receive RS-232 and V.28 communications interface with automatic shutdown/wake-up features and high data rate capabilities. It achieves a low 1µA supply current with the revolutionary AutoShutdown™ feature. AutoShutdown saves power without changes to the existing BIOS or operating system by entering low-power shutdown mode when the RS-232 cable is disconnected or when the transmitter of the connected peripheral is off. The MAX221E wakes up and drives the INVALID pin high when an active RS-232 cable is connected, signalling the host that a peripheral is connected to the communications port. It is used in applications such as maintenance/diagnostic ports, industrial systems, telecommunications, and set-top boxes.
