DS96172CJ

Overview

The DS96172CJ is a high-performance, low-power quad universal asynchronous receiver/transmitter (QUAD UART) manufactured by National Semiconductor. It integrates four independent UART channels within a single package, designed for applications requiring multiple serial communication interfaces. The device supports standard RS-232 and RS-485 protocols, providing flexible data transmission capabilities. It operates with a wide supply voltage range and includes integrated clock generators to reduce external component count. The unit is housed in a standard plastic DIP package suitable for through-hole mounting on printed circuit boards.

Feature Summary

• Integrates four independent UART channels for multi-port serial connectivity
• Supports both RS-232 and RS-485 communication standards
• Includes internal clock generation to minimize external requirements
• Designed for low power consumption in industrial environments

Applications

• Industrial automation control systems
• Multi-port data acquisition equipment
• Telecommunications interface modules
• Embedded system serial expansion

Procurement Notes

Verify the specific suffix 'CJ' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding pin assignments and voltage levels before procurement.

Selection Notes

Select this component when four separate serial ports are required in a compact form factor. Compare pinout compatibility with legacy designs if replacing older UART controllers. Verify that the operating temperature range meets the environmental specifications of the target application.

Part Context

This part belongs to the National Semiconductor QUAD UART family, which provides consolidated serial communication solutions. It serves as an alternative to using four discrete UART chips, saving board space and simplifying design complexity for systems needing extensive serial I/O.

Replacement Considerations

Check for direct pin-compatible replacements from Texas Instruments or other manufacturers if National Semiconductor products are discontinued. Verify electrical parameter equivalence for voltage and speed.
