The ISL4260E contains 3.0V to 5.5V powered RS-232 transmitters/receivers which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Targeted applications are PDAs, Palmtops, and cell phones where the low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with a manual powerdown function reduces the standby supply current to a 150nA trickle. Tiny 5mm x 5mm Quad Flat No- Lead (QFN) 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 ISL4260E features a VL pin that adjusts the logic pin (see Pin Descriptions table) output levels and input thresholds to values compatible with the VCC powering the external logic (e.g., a UART).
The single pin powerdown function (SHDN = 0) disables all the receiver and transmitter outputs, while shutting down the charge pump to minimize supply current drain.
