DESCRIPTION The ST26C32A is a quad differential line receiver designed to meet the RS-422, RS-423 standards for balanced and unbalanced digital data transmission, while retaining the low power characteristics of CMOS. The ST26C32A has an input sensitivity of 200mV over the common mode input voltage range of 7V. The ST26C32A features internal pull-up and pull-down resistors which prevent output oscillation on unused channels. The ST26C32A provides an enable and disable function to all four receivers and features 3-STATE output with 6mA source and sink capability. ORDERING CODES
