A unique architecture provides very stable propagation delays and low skew over a wide input mon mode, input overdrive and ambient temperature range. Propagation delay is 18ns ± 3ns, while typically t PLH/t PHL skew is 500ps and channel-to-channel skew is 400ps. Each receiver translates differential input levels (VID ≥ 100m V) into valid CMOS and TTL output levels. Its high input resistance (≥ 18k) allows many receivers to be connected to the same driver. The receiver outputs go into a high impedance state when disabled. Protection Features include thermal shutdown and a controlled maximum short-circuit current (50m A max) that does not oscillate in and out of short-circuit mode. Input resistance remains ≥ 18k when the device is unpowered or disabled, thus allowing the LTC1520 to be hot swapped into a backplane without loading the data lines. The LTC1520 operates from a single 5V supply and draws 12m A of supply current. The part is available in a 16-lead narrow SO package.
