Overview
The DS26LS32CN/NOPB is a quad differential line receiver manufactured by Texas Instruments, adhering to the RS-422 standard. It integrates four independent receivers within a single package. The device operates with a supply voltage range of 4.75 V to 5.25 V and supports data rates up to 10 Mb/s. It features Schmitt trigger inputs for noise immunity and is housed in a 16-pin SOIC surface-mount package. The component functions as a receiver-only interface, converting differential signals to single-ended logic levels.
Feature Summary
- Integrates four independent differential line receivers compliant with RS-422 standards
- Utilizes Schmitt trigger inputs to enhance noise immunity on the transmission line
- Designed for high-speed data reception with support for data rates up to 10 Mb/s
Applications
- RS-422 serial communication interfaces
- Industrial control systems requiring differential signal reception
- Data acquisition networks utilizing multi-drop configurations
Procurement Notes
Verify the manufacturer designation, as National Semiconductor was acquired by Texas Instruments. Confirm the presence of the NOPB suffix indicating lead-free compliance. Ensure the package type matches the required SOIC-16 footprint for PCB layout compatibility before ordering.
Selection Notes
Select this component when a quad receiver configuration is required without integrated drivers. Compare against the AM26LS32ACDR if driver functionality is needed. Verify that the 5V supply voltage aligns with the system power architecture and that the 10 Mb/s speed meets the application requirements.
Part Context
This part belongs to the DS26LS32 family of quad differential line receivers. It serves as a successor or equivalent to legacy National Semiconductor parts like the DS26LS32CN. The device is functionally compatible with other industry-standard RS-422 receivers, facilitating upgrades in existing designs.
Replacement Considerations
The AM26LS32ACDR from Texas Instruments is a direct functional replacement. Other compatible alternatives include the SN75ALS193 and MC3486, provided pinouts and electrical characteristics are verified.
