ANALOG DEVICES LTC1518CS#PBF

LTC1518 is a high speed, precision delay differential quad bus/line receiver. A unique architecture provides very stable propagation delays and low skew over wide input common mode, input overdrive and ambient temperature ranges. 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). Input resistance remains ≥22k when the device is unpowered or disabled, thus allowing hot swapping without loading the data lines. It is widely used in application such as high speed RS485/RS422 receivers, STS-1/OC-1 data receivers, PECL line receivers, level translators, fast-20/fast-40 SCSI receiver etc.
