The AM26C31CN is a quad differential line driver manufactured by Texas Instruments. It is a surface mount,16-pin PDIP tube, and is configured to work with RS-422 differential line standards. It has four separate differential outputs, each capable of transmitting both negative and positive logic signals. The drivers are suitable for use in multidrop systems up to distances of 15 meters, at data rates up to 1 Mbps. All four outputs are enabled when the device receives a high logic level on the enable line. The device has latched inputs to regulate the output to its low power standby state when enabled and is rated to operate from -40 degrees Celsius to +85 degrees Celsius.
