The ICL3221E, ICL3223E, and ICL3243E devices conserve system power automatically through an automatic power-down function. When no valid RS-232 voltages are sensed on any receiver input for 30µs, the devices will enter power-down mode, resulting in significant power savings. In this mode, the supply current drops to 1µA, the on-chip charge pump turns off, and the transmitter outputs three-state. This micro-power mode makes these devices ideal for battery-powered and portable applications.

The Intersil ICL32xxE devices are 3.0V to 5.5V powered RS-232 transmitters/receivers designed to meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. They provide ±15kV ESD protection on transmitter outputs and receiver inputs, making them suitable for applications such as PDAs, Palmtops, and notebook computers where low power consumption is critical. These devices feature efficient on-chip charge pumps, manual and automatic power-down functions, and small footprint packaging to ensure board space savings. Data rates greater than 250kbps are guaranteed at worst case load conditions.
