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 po

ISL8563 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. Table 1 summarizes the features of the device represented
