Hot-selling and scarce ICL3243EIAZ-T ESD Protection for RS-232 I/O Pins to 15kV SSOP28 spot stock

Product Descriptions

The Intersil ICL32xxE devices are 3.0V to 5.5V  powered RS-232 transmitters/receivers which meet  ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, they provide ±15kV ESD  protection (IEC61000-4-2 Air Gap and Human Body  Model) on transmitter outputs and receiver inputs (RS- 232 pins). Targeted applications are PDAs, Palmtops,  and notebook and laptop computers 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 (except for the ICL3232E), reduce the  standby supply current to a 1µA trickle. Small footprint  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. This family is fully compatible with 3.3Vonly systems, mixed 3.3V and 5.0V systems, and  5.0V-only systems.

The ICL324XE are 3-driver, 5-receiver devices that  provide a complete serial port suitable for laptop or  notebook computers. Both devices also include  noninverting always-active receivers for “wake-up”  capability.
