ANALOG DEVICES LTC1518CS#PBF Receiver, RS422, RS485, 52 Mbps, 4 Receivers, 4.75 to 5.25V, 0 to 70 °C, NSOIC-16

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.

• Input-to-output propagation delay is 18.5ns typical
