The SN75189DR from Texas Instruments is a monolithic, low-power Schottky quadruple line receiver. It is designed to meet the requirements of the standard interface between data-terminal equipment and data-communication equipment as defined by TIA/EIA-232-F.
This receiver operates from a single 5V supply and features built-in input hysteresis for improved noise immunity. It supports data rates up to 1 Mbps and has an input signal range of ±30 V. The device is available in a 14-SOIC package and is suitable for surface mount applications.
Each receiver includes a separate response-control terminal that allows for input threshold shifting and input noise filtering. The SN75189DR is interchangeable with Motorola MC1489 and MC1489A.
Key electrical specifications include a logic voltage of 5V, a main supply voltage of 5V, and an operating temperature range of 0°C to 70°C. The input resistance ranges from 3 kΩ to 7 kΩ.
