... GND * QFN ONLY 14 ISL81334, ISL41334 Detailed Description Each of the two ISLX1334 ports supports dual protocols: RS-485/422, and RS-232. RS-485 and RS-422 are differential (balanced) data transmission standards for use in high speed (up to 20Mbps) networks, or long haul and noisy environments. The differential signaling, coupled with RS-485’ ...

... Rx outputs are short circuit protected, and are only tri- statable when the entire IC is shutdown via the ON/OFF pin, or via the active low RXEN pin available on the QFN package option (see “ISL41334 Special Features” for more details). Tx Features RS-232 drivers invert and convert the standard TTL/CMOS levels from a UART, or µ ...

... IC is forced into SHDN, but ISL81334 (SOIC and SSOP) receiver outputs are not independently tri-statable. ISL41334 (QFN) receiver outputs are tri-statable via an active low RXEN input for each port (see “ISL41334 Special Features” for more details). Tx Features The RS-485/422 driver is a differential output device that delivers at least 2.2V across a 54Ω ...

... Higher data rates require faster edges, so both the ISLX1334 versions offer an edge rate capable of 20Mbps data rates. The ISL41334 also offers two slew rate limited edge rates to minimize problems at slower data rates. Nevertheless, for the best jitter performance when driving long cables, the faster speed settings may be preferable, even at low data rates. See the “ ...

... Connecting the V CC power supply of the logic device - as shown in Figure 12 - limits the ISL41334’s Rx output V and reduces the Tx and control input switching points to values compatible with the logic device output levels. Tailoring the logic pin input switching points and output levels to the supply voltage of the UART, ASIC, or µ ...
