Overview: Datasheet ICL3238E
±15kV ESD Protected, +3V to +5.5V, 10nA, 250kbps, RS-232 Transceiver with Enhanced Automatic Powerdown The ICL3238E contains 3.0V to 5.5V powered RS-232 transmitters/receivers that meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. It provides ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are cell phones, Palmtops, and data cables in which the low operational power consumption and even lower standby power consumption is critical. Efficient on-chip charge pumps coupled with manual and enhanced automatic powerdown functions reduce the standby supply current to a 10nA trickle. Small footprint packaging and the use of small, low value capacitors ensure board space savings. Data rates greater than 250kbps are ensured at worst-case load conditions and provide compatibility with popular PC communication software.
The ICL3238E is a five driver, three receiver device optimized for DCE applications with full hardware handshaking. It includes a noninverting, always-active receiver for RING INDICATOR monitoring.
