LTC1519IS#PBF

LTC1519 is a high speed, precision delay differential quad bus/line receiver that can operate at data rates as high as 52Mbps. A unique architecture provides very stable propagation delays and low skew over wide input common mode, input overdrive and ambient temperature ranges. Each receiver translates differential input levels (VID≥300mV) into valid CMOS and TTL output levels. Its high input resistance (≥22K) allows many receivers to be connected to the same driver. The receiver outputs go into a high impedance state when disabled. This receiver have a fail-safe feature that guarantees a high output state when the inputs are shorted or left floating. Other protection features include thermal shutdown and a controlled maximum short-circuit current (50mA max). It is used in application like high speed RS485/RS422 receivers, STS-1/OC-1 data receivers, PECL line receivers, level translators, fast-20/fast-40 SCSI receiver etc.
