SN75C189D Description

Short technical summary and product information.

The SN75C189D from Texas Instruments is a quadruple low-power line receiver conforming to TIA/EIA-232-F and ITU Recommendation V.28 standards. It is designed to interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE).

 

This receiver features a typical hysteresis of 330 mV, ensuring reliable signal reception. It operates within a voltage range of 4.5V to 6V and has a maximum data rate of 1 Mbps. The device includes an on-chip filter that rejects input pulses shorter than 1 µs, with the option for external capacitor filtering for enhanced noise rejection.

 

The SN75C189D is suitable for applications requiring RS232 communication. It operates across a temperature range of 0°C to 70°C. The component is supplied in a 14-SOIC package, designed for surface mounting.

 

This part is functionally interchangeable and pin-to-pin compatible with Texas Instruments SN75189/SN75189A and Motorola MC1489/MC1489A.
