AM26C32CN

AM26C32CN Description

The AM26C32CN from Texas Instruments is a quad differential line receiver designed for robust data transmission in industrial and communication systems. It operates within a 4.5V to 5.5V supply range and supports RS422 and RS423 protocols, making it ideal for noise-immunity-critical applications. Housed in a 16-pin DIP (Through Hole) package, this obsolete but reliable component features 60 mV of receiver hysteresis, enhancing signal integrity in electrically noisy environments. With an operating temperature range of 0°C to 70°C, it is suited for moderate industrial conditions.
