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.

Features:

D Input Voltage Range of 7V (differential or common mode)
D ±0.2V Sensitivity over the Input Voltage Range
D Meets all the Requirements of RS–422 and RS–423
D 6k Minimum Input Impedance
D 30mV Input Hysteresis
D Operation from Single +5V Supply
D Fail Safe Input–Output Relationship. Output Always High when Inputs are Open
D 3–State Drive, with Choice of Complementary Output Enables, for Receiving Directly onto a

Data Bus

D Propagation Delay 17ns Typical
D Advanced Low–Power Schottky Processing
D 100% Reliability Assurance Screening Requirements
