The DS26C32A is a quad differential line receiver designed to meet the RS-422, RS-423, and Federal Standards 1020 and 1030 for balanced and unbalanced digital data transmission, while retaining the low power characteristics of CMOS. The DS26C32A has an input sensitivity of 200 mV over the common mode input voltage range of 7V. The DS26C32A features internal pull-up and pull-down resistors which prevent output oscillation on unused channels.
