Overview
The National Semiconductor 4703BDM is a CMOS asynchronous First-In, First-Out (FIFO) memory buffer. It provides a data storage capacity of 16 words by 4 bits. The component operates as an independent dual-port device, allowing simultaneous read and write operations using separate clock domains for input and output. This architecture facilitates efficient data buffering and protocol conversion between systems with different timing requirements.
Feature Summary
- Asynchronous dual-port operation enabling independent read and write clocks
- CMOS technology for low power consumption and high noise immunity
- Dedicated status flags indicating empty and full conditions
Applications
- Data buffering in digital communication interfaces
- Protocol conversion between asynchronous systems
- Temporary data storage in microprocessor-based designs
Procurement Notes
Verify the manufacturer origin, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix 'BDM' matches the required package and temperature grade. Request official datasheets to validate pin compatibility and electrical specifications before integration into production designs.
Selection Notes
Select this component when interfacing systems requiring 16x4 word depth with independent clock domains. Ensure supply voltages align with standard CMOS logic levels. Evaluate jitter tolerance and duty cycle distortion limits to maintain setup and hold time margins during high-frequency operation.
Part Context
This part belongs to the National Semiconductor FIFO family, designed for general-purpose data buffering. It utilizes standard CMOS fabrication processes typical of its era. The device serves as a foundational building block for managing data flow in legacy and specialized industrial control applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference availability through authorized distributors or TI catalogs if sourcing from current inventory.
