ISL83387E
±15kV ESD Protected, +3V to +5.5V, 1Microamp, 250kbps, RS-232 Transceivers with Enhanced Automatic Powerdown
The ISL83387E is a 3.0V to 5.5V powered RS-232 transceiver that meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, 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 industrial laptop computers, Palmtops, PDAs, and notebooks where 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 1µA trickle. The TSSOP 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.
The ISL83387E features a VL pin that adjusts the logic pin output levels and input thresho.
