SN74LS169BD

Counter Dividers Overview

The SN74LS169BD is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments. It operates within the standard LS logic series and features bidirectional counting capabilities controlled by an up/down input pin. The device utilizes positive-edge triggering for clock synchronization. It is housed in a 16-pin SOIC surface-mount package, designed for operation with a supply voltage range of 4.75 V to 5.25 V and an operating temperature range of 0°C to 70°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting architecture
• Bidirectional up/down counting control
• Positive-edge triggered clock operation

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation

Counter Dividers Procurement Notes

Verify the specific suffix 'BD' against the official datasheet to confirm the 16-SOIC package type and commercial temperature grade. Ensure the order matches the required logic family specifications for the target application environment.

Counter Dividers Selection Notes

Select this component when a synchronous, bidirectional 4-bit counter is required in a surface-mount design. Compare performance against the SN74LS191 if higher speed or different packaging options are needed for the system requirements.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74LS series of logic integrated circuits. It serves as a fundamental building block for sequential logic designs requiring precise state tracking and direction control in digital systems.

Counter Dividers Replacement Considerations

The SN74LS169BD is functionally equivalent to the SN74LS169BDR (tape and reel version) and the SN74LS169AN (through-hole DIP version). Verify package compatibility before substitution.
