Features, Applications

The is a Schottky dual differential line receiver which has been specifically designed to satisfy the requirements of EIA Standards RS-422 and RS-423. In addition, the DS9637A satisfies the requirements of MIL-STD 188-114 and is compatible with the International Standard CCITT recommendations. The DS9637A is suitable for use as a line receiver in digital data systems, using either single ended or differential, unipolar or bipolar transmission. It requires a single 5V power supply and has Schottky TTL compatible outputs. The DS9637A has an operational input common mode range 7V either differentially or to ground.

Features

Dual channel Single 5V supply Satisfies EIA standards RS-422 and RS423 Built-in 35 mV hysteresis High input common mode voltage range High input impedance TTL compatible outputs Schottky technology Extended temperature range

Note 2: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices should be operated at these limits. The tables of "Electrical Characteristics" provide conditions for actual device operation. Note 3: Unless otherwise specified Min/Max limits apply across the to +125C temperature range for DS9637AM and across the to +70C range for the DS9637ASC. All typicals are given for VCC = 5V and = 25C. Note 4: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are referenced to ground unless otherwise specified. Note 5: Only one output at a time should be shorted. Note 6: VDIFF (Differential Input Voltage) = (VI+) - (VI-). VCM (Common Mode Input Voltage) = VI+ or VI-. Note in series with inputs. Note 8: The input not under test is tied to ground.
