FN6002.2
+/-15kV ESD Protected, +3V to +5.5V,
1Microamp, 250kbps, EIA/TIA-562,
EIA/TIA-232 Transmitters/Receivers
The Intersil ISL8563E contains 3.0V to 5.5V powered
transmitters/receivers which meet ElA/TIA-562 and
ElA/TIA-232 specifications, even at V_CC = 3.0V. Additionally,
they provide ±15kV ESD protection (IEC61000-4-2 Air Gap
and Human Body Model) on transmitter outputs and receiver
inputs (RS-562 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 a manual powerdown function, 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. The
ISL8563E is fully compatible with 3.3V only systems, mixed
3.3V and 5.0V systems, and 5.0V only systems.
This product features an improved charge pump which
delivers ±5V transmitter supplies, allowing the use of the
ISL8563E in RS-562 and RS-232 applications. RS-562
applications will benefit from the improved noise immunity
afforded by the ±5V output swing capability.
