SN74ALS569ANS

Counter Dividers Overview

The SN74ALS569AN is a synchronous 4-bit binary up/down counter manufactured by Texas Instruments. It features 3-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device supports counting frequencies up to 30 MHz at maximum voltage. Propagation delays from clock to output range from 4 ns to 19 ns depending on the specific transition. It includes asynchronous and synchronous clear functions, as well as programmable load capabilities.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with up or down direction control
• 3-state outputs for direct bus line driving
• Programmable parallel data loading via dedicated inputs
• Fully cascadable design with ripple-carry and clocked carry outputs

Counter Dividers Applications

• Digital frequency counters
• Timing sequence generators
• Event counting systems
• Programmable delay lines

Counter Dividers Procurement Notes

Verify that the ordering suffix matches 'N' for the standard plastic DIP package. Confirm the manufacturer is Texas Instruments to ensure compatibility with the specified electrical characteristics. Check RoHS compliance status if required for your assembly process. Ensure the component is sourced from authorized distributors to avoid counterfeit parts.

Counter Dividers Selection Notes

Select this component when a synchronous binary counter with 3-state outputs is required. It is suitable for designs needing both asynchronous and synchronous reset options. Consider the 30 MHz maximum clock frequency for high-speed applications. Verify that the 20-pin PDIP package fits the available board space.

Counter Dividers Part Context

This part belongs to the SN54/74ALS series of logic integrated circuits. It is functionally related to the SN74ALS568A decade counter variant. The ALS series offers improved speed-power product compared to earlier standard TTL families. This specific model handles binary counting rather than decimal counting.

Counter Dividers Replacement Considerations

SN74ALS568AN serves as a functional substitute for decade counting applications.
