MAX221EAE+T by Analog Devices

+5V, 1µA, 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 1µA 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.
