54F399/B2A

Overview

The 54F399/B2A is a high-speed quad 2-port register manufactured by Rochester Electronics, LLC. It functions as a dual-marked component under specification M38510/35002B2A. The device selects 4-bit data from two distinct data sources, referred to as ports, under the control of a common select input (S). This architecture allows for efficient routing of parallel data streams in digital logic applications requiring multiplexing capabilities.

Feature Summary

• Quad 2-port register configuration for parallel data handling
• Common select input controls data source selection
• High-speed operation suitable for digital logic systems

Applications

• Digital data routing and switching
• Parallel bus interface management
