4076BDC

Overview

The National Semiconductor 4076BDC is a D-type flip-flop integrated circuit containing four independent bits per element. It features tri-state, non-inverted outputs and operates with a positive edge trigger type. The device supports a maximum clock frequency of 19 MHz and exhibits a maximum propagation delay of 75 ns at 15 V with a 50 pF load. It is housed in a 16-pin plastic DIP package and functions within an operating temperature range of -40 °C to 85 °C.

Feature Summary

• Contains four independent D-type flip-flops within a single package
• Provides tri-state output capability for bus-oriented applications
• Utilizes positive edge triggering for data synchronization
• Features non-inverted output polarity

Applications

• Digital data storage and register circuits
• Shift register configurations
• Timing and control logic systems
• State machine implementations

Procurement Notes

Verify the specific manufacturer designation, as National Semiconductor assets are now managed by Texas Instruments. Confirm that the 'DC' suffix corresponds to the required commercial temperature grade and plastic DIP packaging. Ensure compatibility with existing 4000-series CMOS voltage levels and check for RoHS compliance status relative to current supply chain requirements.

Selection Notes

Select this component when four synchronized D-type latches with high-impedance outputs are required. It is suitable for designs needing positive edge triggering and non-inverted logic states. Consider the 19 MHz speed limit and 75 ns delay for timing constraints. Verify package availability and thermal ratings against the application environment.

Part Context

This part belongs to the standard 4000-series CMOS logic family, known for wide supply voltage ranges and low power consumption. As a discrete flip-flop, it serves as a fundamental building block for sequential logic. The 4076BDC specifically integrates four elements, reducing board space compared to using individual single-bit devices.

Replacement Considerations

Public confirmed substitute part numbers include MN4076B from Panasonic, which shares identical logical functionality and pinout specifications.
