MAX221 +5V, 1�A, Single RS-232 Transceiver With AutoShutdown

The MAX221 is a +5V-powered, single transmit/receive RS-232 and V.28 Communications Interface with Automatic shutdown/wake-up features and high data rate capabilities.
The MAX221 achieves a low 1A supply current with Maxim's 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 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. For an equivalent RS-232 transceiver with enhanced 15kV ESD protection, refer to the MAX221E data sheet.
