DM74ALS169BMX

Counter Dividers Overview

The DM74ALS169BMX is a synchronous presettable binary counter manufactured by Fairchild Semiconductor. It features internal carry look-ahead for high-speed cascading applications. The device operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 16-SOIC package and functions as a positive-edge triggered 4-bit counter.

Counter Dividers Feature Summary

• Synchronous presettable operation with internal carry look-ahead
• Supports up/down counting direction
• Positive edge triggering mechanism

Counter Dividers Applications

• High-speed counting applications requiring cascading
• Digital systems utilizing synchronous presettable counters
• Binary counting circuits in logic designs

Counter Dividers Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor's logic division is now part of ON Semiconductor. Confirm the specific suffix 'BMX' corresponds to the 16-SOIC package and bulk or tape-and-reel configuration required for your assembly process. Ensure compatibility with 74ALS logic family voltage levels.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with up/down capability is required. The internal carry look-ahead makes it suitable for high-speed applications where propagation delay limits performance in asynchronous chains. Verify that the operating voltage aligns with the 4.5 V to 5.5 V specification.

Counter Dividers Part Context

This component belongs to the 74ALS series of logic devices, known for advanced low-power Schottky technology. It serves as a standard binary counter element within digital logic families, providing reliable counting functionality in integrated circuit form factors compatible with surface-mount assembly techniques.

Counter Dividers Replacement Considerations

Compatible substitutes include other 74ALS169 variants from different manufacturers, such as those produced by Texas Instruments or National Semiconductor, provided they maintain the same pinout and electrical characteristics. Verify package compatibility before substitution.
