SN74AS867FN

Counter Dividers Overview

The SN74AS867FN is an 8-bit binary counter from the Texas Instruments 74AS series. It features a positive-edge triggered architecture with asynchronous reset functionality and supports both up and down counting directions. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 24-pin plastic dual in-line package (PDIP). It is designed for through-hole mounting and functions reliably across a commercial temperature range of 0°C to 70°C.

Counter Dividers Feature Summary

• Executes 8-bit binary counting operations using positive-edge triggering mechanisms.
• Provides asynchronous reset capability for immediate state initialization.
• Supports bidirectional counting sequences including both up and down modes.

Counter Dividers Applications

• Digital frequency division circuits
• Binary sequence generation systems
• Timing control logic modules

Counter Dividers Procurement Notes

Verify the specific suffix 'FN' against official manufacturer documentation to confirm the exact package type and material composition. Ensure that the required operating temperature range aligns with the commercial grade specifications. Confirm availability status as this component may be subject to discontinuation notices or lifecycle changes.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous counting solution with high-speed AS-series performance is required. Consider the 24-pin DIP package constraints for board layout. Verify that the 4.5 V to 5.5 V supply requirement matches the system power rails. Evaluate the asynchronous reset feature against alternative counters with synchronous reset options.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74AS logic family, known for advanced Schottky technology. It serves as a digital counter element within larger sequential logic designs. The 74AS series typically offers faster propagation delays compared to standard TTL counterparts while maintaining compatible pinouts.
