Description
Key features include a wide supply voltage range from 4.75V to 5.25V, low power consumption with a shutdown mode, and a fail-safe receiver that guarantees a logic-high output when the input is open, shorted, or terminated but undriven. It offers ESD protection up to ±15kV and is capable of driving loads up to 60mA. The device is optimized for data rates up to 2.5Mbps and is suitable for use in industrial and commercial applications, such as networking equipment, industrial control, and building automation systems. The "T" in its part number indicates that it is available in a tape and reel packaging for automated assembly processes.
