Features
• Drop in Replacement for MAX563, with Improved Output
Voltage (±5V) for Enhanced Noise Immunity
The Intersil ISL8563 contains 3.0V to 5.5V powered
transmitters/receivers which meet ElA/TIA-562 and
• Available as ±15kV ESD Protected Version (ISL8563E)
• Meets EIA/TIA-562, and EIA/TIA-232 Specifications at 3V
• Latch-Up Free
ElA/TIA-232 specifications, even at V
= 3.0V. 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 ISL8563 is fully compatible with 3.3V only
systems, mixed 3.3V and 5.0V systems, and 5.0V only
systems.

Applications
This product features an improved charge pump which
delivers ±5V transmitter supplies, allowing the use of the
ISL8563 in RS-562 and RS-232 applications. RS-562
applications will benefit from the improved noise immunity
afforded by the ±5V output swing capability.
