ICL3243 Datasheet | Renesas

feature an automatic powerdown function that powers down the on-chip power-supply and driver circuits. Power-down occurs when an attached peripheral device is shut off or the RS-232 cable is removed, conserving system power automatically without changes to the hardware or operating system. These devices power up again when a valid RS-232 voltage is applied to any receiver input. Table 1 on page 6 summarizes the features of the devices represented by this datasheet, while Application Note AN9863 summarizes the features of each device prising the ICL32xx 3V family.
