NTE2632 Integrated Circuit Quad Differential Line Receiver Functional Description: The NTE2632 is a quad line receiver constructed using Advanced Low–Power Schottky processing in a 16–Lead DIP type package designed to meet the requirements of RS–422 and RS–423, and federal standards 1020 and 1030 for balanced and unbalanced digital data transmission. This device features and input sensitivity of 200mV over the input voltage range of ±7V. The NTE2632 provides an enable and disable function common to all four receivers and features 3–state outputs with 8mA sink capability. This device also incorporates a fail safe input–output relationship which keeps the outputs high when the inputs are open.
