ISL3241E, ISL3243E QFN Packaged, ±15k V ESD Protected, +2.7V to +3.6V, 250kbps, RS-232 Transmitters/Receivers with Separate Logic Supply Pin FN6768 Rev 2.00 June 18, 2012 The Intersil ISL324x E devices are 2.7V to 3.6V powered RS-232 transmitters/receivers which meet El A/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, they provide ±15k V ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are POS systems, and notebook and laptop puters where the low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with manual and automatic power-down functions, reduce the standby supply current to a 0.5µA trickle. Tiny 5mmx5mm Quad Flat No-Lead (QFN) packaging and the use of small, low value capacitors ensure board space savings as well. Data rates greater than 250kbps are guaranteed at worst case load conditions. ISL32...
