SN75ALS194NSR

Drivers, Receivers, Transceivers Overview

The SN75ALS194NSR is a quad differential line driver manufactured by Texas Instruments, designed for RS-422 interface applications. It operates within a supply voltage range of 4.75 V to 5.25 V, with a typical operating voltage of 5 V. The device supports data rates up to 20 Mb/s and features a propagation delay of 6 ns. It draws a maximum operating supply current of 45 mA and dissipates up to 1.15 W of power. The component is housed in a 16-SOIC package (SOIC-16) suitable for surface mount installation. It functions without a shutdown mode and operates reliably across a temperature range from 0°C to +70°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix NSR confirms the SOIC-16 package and tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration. Ensure the component matches the required thermal and electrical specifications for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad driver configuration is required for RS-422 applications. Compare propagation delay and power dissipation against system timing constraints. Verify that the 16-SOIC package fits the PCB layout requirements. Consider alternative packages like PDIP if through-hole mounting is necessary, noting potential differences in delay characteristics.
