+3V to +5.5V, 1Microamp, 250kbps,
EIA/TIA-562, EIA/TIA-232
Transmitters/Receivers
The Intersil ISL8563 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. 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 1碌A(chǔ) 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
鹵
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
鹵
5V output swing capability.
Table 1 summarizes the features of the device represented
by this data sheet, while Application Note AN9863
summarizes the features of each device comprising the 3V
RS-232 family.
For a drop-in compatible part with
鹵15kV
ESD protection,
please see the ISL8563E data sheet.
