Maxim Integrated MAX221CAE+ Line Transceiver SSOP

The MAX221 is a +5V-powered, single transmit/receive communications interface with automatic shutdown/wake-up features and high data rate capabilities.
The MAX221 achieves a low 1μA supply current with Maxim's AutoShutdown™ feature. AutoShutdown saves power without changes to the existing BIOS or operating system by entering low-power shutdown mode when the cable is disconnected, or when the transmitter of the connected peripheral is off. The MAX221 wakes up and drives the active-low INVALID pin high when an active RS-232 cable is connected, signaling the host that a peripheral is connected to the communications port.
The MAX221 is available in a 16-pin SSOP package as well as a 16-pin TSSOP that uses 50% less board space than a 16-pin SO.
