DATASHEET
ISL83387E FN6040
Rev 1.00
July 8, 2005 +/-15kV ESD Protected, +3V to +5.5V, 1Microamp, 250kbps, RS-232 Transceivers
with Enhanced Automatic Powerdown and a Separate Logic Supply
The Intersil ISL83387E is a 3.0V to 5.5V powered RS-232
transceiver which meets ElA/TIA-232 and V.28/V.24
specifications, even at VCC = 3.0V. Additionally, it provides
п‚±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 enhanced automatic powerdown functions, reduce the
standby supply current to a 1пЃ­A trickle. TSSOP 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.
The ISL83387E features a VL pin that adjusts the logic pin
output levels and input thresholds to values compatible with
the VCC powering the external logic (e.g., a UART).
