+/-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 (IEC 1000-4-2 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.
