Texas Instruments SN75ALS170 Triple Differential Bus Transceiver SN75ALS170DW

The SN75ALS170DW is a triple differential bus transceiver designed for bidirectional data communication on multipoint bus transmission lines. It complies with ANSI Standards EIA/TIA-422-B and RS-485, as well as ITU Recommendation V.11, making it suitable for balanced transmission lines in noisy environments. The device operates from a single 5-V power supply and supports data rates of up to 20 million transfers per second, with the capability to handle data pulses as short as 30 ns. This transceiver features independent direction controls for each channel, allowing for flexible data flow management. It includes thermal shutdown protection, driver output capacity of ¬±60 mA, and receiver input sensitivity of ¬±300 mV maximum. The SN75ALS170DW is characterized for operation within a temperature range of 0¬8C to 70¬8C and offers glitch-free power-up and power-down protection. Its wide common-mode voltage range makes it suitable for party-line applications, providing minimal loading to the bus when disabled.
