• Edge-triggered operational mode
• Fully decoded terminal count output
• Cascadable design for multi-stage expansion

Applications

• Memory addressing systems
• Frequency division circuits
• Digital counting modules

Procurement Notes

Verify the specific suffix BEA against official datasheets to confirm package type and temperature range. Ensure compatibility with existing logic levels and power supply requirements before integration. Confirm that the component meets all necessary environmental and electrical standards for the intended deployment environment.

Selection Notes

Select this component when a synchronous BCD decade counter with preset functionality is required. It is suitable for designs needing high-speed synchronous expansion capabilities. Consider its edge-triggered nature for timing-sensitive applications where precise clock synchronization is critical for system stability.

Part Context

This part belongs to the LS160 series of synchronous counters. It is functionally equivalent to other industry-standard BCD decade counters but may differ in pinout or electrical characteristics depending on the manufacturer. It serves as a fundamental building block in digital logic design for sequential operations.
