Transmitters/Receivers

The Intersil ISL8563 contains 3.0V to 5.5V powered

transmitters/receivers which meet ElA/TIA-562 and

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 1

µA 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.

This product features an improved charge pump which

delivers

ISL8563 in RS-562 and RS-232 applications. RS-562

applications will benefit from the improved noise immunity

afforded by the

Table 1 summarizes the features of the device represented
