SN74ALS569ADWR

Counter Dividers Overview

The SN74ALS569ADWR is a Fast (ALS) series, synchronous, positive edge-triggered 4-bit bidirectional binary counter manufactured by Texas Instruments. It features a 20-pin SOIC package and supports bidirectional counting operations with clocked carry output capabilities. The device operates within a supply voltage range of 4.5 V to 5.5 V and functions at temperatures from 0°C to +70°C. It utilizes TTL-compatible inputs and provides high-speed performance suitable for complex digital logic applications requiring reliable binary counting.

Counter Dividers Feature Summary

• Synchronous positive edge-triggered operation ensures precise timing control for data transitions.
• Bidirectional binary counting capability allows flexible up or down counting sequences based on control signals.
• Clocked carry output facilitates cascading multiple counters for extended bit-width applications without external gating.

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific suffix 'ADWR' confirms the SOIC-20 tape-and-reel packaging variant. Confirm RoHS compliance status as original records indicate non-compliance for some variants. Ensure the operating temperature range meets system requirements. Validate that the manufacturer is Texas Instruments to avoid counterfeit components.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with bidirectional functionality is required in an ALS logic family. Consider the SOIC-20 package constraints for PCB layout. Verify input compatibility with driving TTL sources. Evaluate power consumption against system thermal limits given the ALS series characteristics.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74ALS569 family of synchronous counters. It is distinct from latches like the SN74ALS373A and flip-flops like the SN74ALS577A. The ALS series offers improved speed-power product compared to standard LS logic. The 'DWR' suffix specifically denotes the reel packaging format for surface-mount assembly.

Counter Dividers Replacement Considerations

SN74ALS569DW: Identical functional equivalent in tube packaging instead of reel.
