The LTC491IS#TR is a low power differential bus transceiver from Linear Technology (LT), designed for multipoint data transmission standards like RS485 and RS422. It supports an extended common mode range from -7V to 12V and a ±7V ground difference between devices.
This CMOS design offers significant power savings with a typical quiescent current (ICC) of 300µA. The driver and receiver feature three-state outputs. For protection, it includes thermal shutdown and power-up/down glitch-free driver outputs, allowing live insertion or removal. The receiver has a fail-safe feature that ensures a high output state when inputs are open.
Specifications are guaranteed from 0°C to 70°C and a 4.75V to 5.25V supply voltage range. The LTC491IS#TR is pin-compatible with the SN75180 and is available in 14-lead PDIP and SO packages. It supports up to 32 transceivers on the bus.
Key electrical characteristics include a typical driver propagation delay of 28ns with 5ns skew for 2.5MB operation, and 70mV typical input hysteresis.
The supply voltage range is 4.75V to 5.25V (single supply).
The operating temperature range is 0°C to 70°C.
The device is available in a 14-Lead surface mount package.
The typical quiescent current is 300µA.
The bus common mode range is -7V to 12V.
Typical driver propagation delay is 28ns.
Typical input hysteresis is 70mV.
