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.
The ICL32xxE family are low‑power RS‑232 transmitters/receivers that operate from 3.0 V to 5.5 V and meet EIA/TIA‑232 and V.28/V.24 specifications. They provide up to +15 kV ESD protection on all I/O pins, automatic and manual power‑down functions, and data rates of at least 250 kbps.
The document includes full pin‑out diagrams, typical operating circuits, ordering information for multiple package types (SSOP, TSSOP, SOIC, PDIP), and detailed mechanical dimensions for shrink‑small‑outline and small‑outline plastic packages.
