SN74ALS569ADW Equivalent & Substitute Parts

Part Overview

The SN74ALS569ADW is a 4-bit binary counter IC manufactured by Texas Instruments, housed in a 20-SOIC surface mount package. This component functions as a synchronous counter with both up and down counting capability, operating at a maximum count rate of 30 MHz. The part is classified as obsolete, making identification of active equivalent components essential for new designs and production continuity. Substitute parts must maintain identical electrical specifications and package dimensions to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74ALS569ADW is determined by strict equivalence across the following critical parameters:

• Logic Function: Binary counter with 4-bit capacity
• Counting Direction: Bidirectional (up/down capability)
• Timing Architecture: Synchronous operation
• Count Rate Performance: 30 MHz maximum
• Electrical Supply: 4.5 V to 5.5 V operating range
• Package Specification: 20-SOIC form factor with 0.295" (7.50mm) width
• Pin Configuration: Identical pinout required for direct substitution

The SN74ALS569ADWR qualifies as a direct substitute based on matching all electrical parameters, identical package dimensions, and compatible pinout. The primary distinction is packaging format (Tape & Reel versus bulk) and active product status.
