ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E 15kV ESD Protected, +3V to +5.5V, 1A, 250kbps, RS-232 Transmitters/Receivers ICL3221E, ICL3222E, ICL3223E, Features ICL3232E, ICL3241E, ICL3243E ESD Protection for RS-232 I/O Pins to 15kV (IEC61000) The Intersil ICL32xxE devices are 3.0V to 5.5V powered Drop in Replacements for MAX3221E, MAX3222E, RS-232 transmitters/receivers which meet ElA/TIA-232 MAX3223E, MAX3232E, MAX3241E, MAX3243E, and V.28/V.24 specifications, even at V = 3.0V. CC SP3243E Additionally, they provide 15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on ICL3221E is a Low Power, Pin Compatible Upgrade for 5V MAX221E transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are PDAs, Palmtops, and notebook ICL3222E is a Low Power, Pin Compatible Upgrade and laptop computers where the low operational, and for 5V MAX242E, and SP312E even lower standby, power consumption is critical. ICL3232E is a Low Power Upgrade for HIN232E, Efficient on-chip charge pumps, coupled with manual and ICL232 and Pin Compatible Competitor Devices automatic power-down functions (except for the RS-232 Compatible with V = 2.7V ICL3232E), reduce the standby supply current to a 1A CC trickle. Small footprint packaging, and the use of small, Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V low value capacitors ensure board space savings as well. Latch-Up Free Data rates greater than 250kbps are guaranteed at worst case load conditions. This family is fully compatible with On-Chip Voltage Converters Require Only Four 3.3V-only systems, mixed 3.3V and 5.0V systems, and External 0.1F Capacitors 5.0V-only systems. Manual and Automatic Power-Down Features The ICL324XE are 3-driver, 5-receiver devices that Guaranteed Mouse Driveability (ICL324xE Only) provide a complete serial port suitable for laptop or Receiver Hysteresis For Improved Noise Immunity notebook computers. Both devices also include noninverting always-active receivers for wake-up Guaranteed Minimum Data Rate 250kbps capability. Wide Power Supply Range Single +3V to +5.5V The ICL3221E, ICL3223E and ICL3243E, feature an Low Supply Current in Power-Down State . 1A automatic power-down function which powers down Pb-Free Available (RoHS Compliant) the on-chip power-supply and driver circuits. This occurs when an attached peripheral device is shut off or the Applications RS-232 cable is removed, conserving system power automatically without changes to the hardware or Any System Requiring RS-232 Communication Ports operating system. These devices power up again when a - Battery Powered, Hand-Held, and Portable valid RS-232 voltage is applied to any receiver input.
