SN65C189AD

Drivers, Receivers, Transceivers Overview

The SN65C189AD is a low-power RS-232 line receiver manufactured by Texas Instruments. It integrates four independent receivers within a single package, designed for serial communication applications requiring high noise immunity and low power consumption. The device operates with a supply voltage of 5 V and supports data rates up to 1 Mb/s. It features ESD protection capabilities and functions reliably across an operating temperature range from 0°C to +70°C. The component is housed in a 14-pin SOIC surface-mount package, drawing a typical operating supply current of 700 uA.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 14-SOIC configuration. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require four separate RS-232 receivers on a single chip. Consider the 14-SOIC package constraints for board space. Verify that the 5 V supply voltage aligns with the system's power architecture and that the 0°C to +70°C operating range meets environmental specifications.
