DATASHEET ICL3221, ICL3222, ICL3223, ICL3232, ICL3241, ICL3243 FN4805 Rev 22.00 One Microamp Supply-Current, +3V to +5.5V, 250kbps, RS-232 September 1, 2015 Transmitters/Receivers The Intersil ICL32XX devices are 3.0V to 5.5V powered Features RS-232 transmitters/receivers which meet ElA/TIA-232 and Pb-Free Plus Anneal Available as an Option V.28/V.24 specifications, even at V = 3.0V. Targeted CC (RoHS Compliant) (See Ordering Info) applications are PDAs, Palmtops, and notebook and laptop 15kV ESD Protected (Human Body Model) computers where the low operational, and even lower standby, power consumption is critical. Efficient on-chip Drop in Replacements for MAX3221, MAX3222, charge pumps, coupled with manual and automatic MAX3223, MAX3232, MAX3241, MAX3243, SP3243 powerdown functions (except for the ICL3232), reduce the ICL3221 is Low Power, Pin Compatible Upgrade for 5V standby supply current to a 1 A trickle. Small footprint MAX221 packaging, and the use of small, low value capacitors ensure ICL3222 is Low Power, Pin Compatible Upgrade for 5V board space savings as well. Data rates greater than MAX242, and SP312A 250kbps are guaranteed at worst case load conditions. This ICL3232 is Low Power Upgrade for HIN232/ICL232 and family is fully compatible with 3.3V only systems, mixed 3.3V Pin Compatible Competitor Devices and 5.0V systems, and 5.0V only systems. RS-232 Compatible with V = 2.7V CC The ICL324X are 3-driver, 5-receiver devices that provide a Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V complete serial port suitable for laptop or notebook computers. Both devices also include noninverting always- Latch-Up Free active receivers for wake-up capability. On-Chip Voltage Converters Require Only Four External The ICL3221, ICL3223 and ICL3243, feature an 0.1F Capacitors automatic powerdown function which powers down the Manual and Automatic Powerdown Features (Except on-chip power-supply and driver circuits. This occurs when ICL3232) an attached peripheral device is shut off or the RS-232 Guaranteed Mouse Driveability (ICL324X Only) cable is removed, conserving system power automatically Receiver Hysteresis For Improved Noise Immunity without changes to the hardware or operating system. These devices power up again when a valid RS-232 Guaranteed Minimum Data Rate . 250kbps voltage is applied to any receiver input. Guaranteed Minimum Slew Rate . 6V/s Table 1 summarizes the features of the devices represented Wide Power Supply Range .
