Renesas Electronics Corporation QFN, ±15kV ESD Protected, +3V to +5.5V, 150nA, 250kbps, RS-232 3-Tx, 2-Rx, with Logic Supply ISL4260EIRZ-T

The ISL4260E contains 3.0V to 5.5V powered RS-232 transmitters/receive rs which meet ElA/TIA-232 and V.28/V.24 specifications, even at VsubCC/sub = 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 bQuad Flat No-Lead/b (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.brbr The ISL4260E features a VsubL/sub pin that adjusts the logic pin (see Pin Descriptions table) output levels and input thresholds to values compatible with the VsubCC/sub powering the external logic (e.g., a UART).brbr The single pin powerdown function (span style="text-decorati on: overline"SHDN/span = 0) disables all the receiver and transmitter outputs, while shutting down the charge pump to minimize supply current drain.
