Description
The ST26C32AB 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 ST26C32AB has an input sensitivity of 200 mV over the common mode input voltage range of ± 7 V. The ST26C32AB features internal pull-up and pull-down resistors which prevent output oscillation on unused channels. The ST26C32AB provides an enable and disable function to all four receivers and features 3-state output with 6 mA source and sink capability.
