ISL8563 TM Data Sheet March 2001 File Number 6005 +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 VCC = 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.
