The LTC490CS8#PBF from LT (Linear Technology Corporation) is a low power differential driver and receiver pair designed for RS485 and RS422 applications. It operates from a single 5V supply with a typical ICC of 300mA. The device supports an extended common mode range of -7V to 12V, allowing for significant ground differences between devices on the bus.
Key features include thermal shutdown protection and power-up/down glitch-free driver outputs, which permit live insertion or removal of the package. The driver maintains high impedance when the power is off. The combined impedance of a driver output and receiver allows up to 32 transceivers on the bus. It also offers 70mV typical input hysteresis and 28ns typical driver propagation delays with 5ns skew for 2.5MB operation.
This transceiver is pin-compatible with the SN75179 and is available in an 8-lead SO package. Both AC and DC specifications are guaranteed over the operating temperature range of 0°C to 70°C and a supply voltage range of 4.75V to 5.25V.
The CMOS design provides significant power savings compared to bipolar counterparts while maintaining ruggedness against overload or ESD damage. The receiver includes a fail-safe feature that guarantees a high output state when the inputs are left open.
