LTC1485CS8#PBF Datasheet PDF - Linear Technology

The LTC1485CS8#PBF is a low power differential bus/line Transceiver designed for multipoint data transmission standard RS485 applications with extended common-mode range. The CMOS with Schottky design offers significant power savings over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage. The driver and receiver feature three-state outputs with the driver outputs maintaining high impedance over the entire common-mode range. Excessive power dissipation caused by bus contention or faults is prevented by a thermal shutdown circuit which forces the driver outputs into a high impedance state. I/O pins are protected against multiple ESD strikes of over ±10kV. The receiver has a fail-safe feature which guarantees a high output state when the inputs are left open.

● Thermal shutdown protection

● Power-up/down glitch-free driver outputs

● Driver maintains high impedance in three-state or with power OFF

● Combined impedance of a driver output and receiver allows up to 32 transceivers on the bus

● 60mV Typical input hysteresis

● Pin-compatible with the SN75176A, DS75176A and SN75LBC176
