SN74LS169BN

Counter Dividers Overview

The SN74LS169BN is a synchronous up/down binary counter from the Texas Instruments 74LS logic family. It features a 4-bit architecture with bidirectional counting capability, triggered by positive edge clocking. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an asynchronous clear input for immediate reset functionality. It is housed in a 16-pin PDIP package suitable for through-hole mounting.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting with bidirectional up/down control
• Positive edge-triggered clock operation for precise timing synchronization
• Asynchronous clear input allows immediate resetting of all count states

Counter Dividers Applications

• Digital frequency division circuits
• Programmable timing sequences
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific suffix 'BN' confirms the 16-pin PDIP through-hole package variant. Confirm the LS logic family designation matches system voltage and speed requirements. Ensure the manufacturer source is Texas Instruments or an authorized distributor to guarantee component authenticity and traceability.

Counter Dividers Selection Notes

Select this component when a synchronous, bidirectional counter is required in a through-hole design. The LS series offers standard propagation delays compatible with moderate-speed digital logic. Verify that the 4-bit capacity meets the application's counting range needs without requiring cascading additional stages.

Counter Dividers Part Context

This part belongs to the widely adopted 74LS (Low-power Schottky) logic family, known for balanced speed and power consumption. The SN74LS169 specifically provides up/down counting capabilities, distinguishing it from unidirectional counters like the SN74LS163. It serves as a fundamental building block for sequential logic designs.

Counter Dividers Replacement Considerations

The SN74LS169BD is documented as a parameter-equivalent alternative. Verify pinout compatibility between the PDIP and SOIC packages if transitioning to surface mount technologies.
