AM25LS2519/BSA

Overview

The AM25LS2519/BSA is a 4-bit D-type flip-flop manufactured by Advanced Micro Devices. It features positive edge triggering and true outputs with 3-state capability. The device operates within a temperature range of -55 °C to 125 °C and utilizes a 20-lead Flat Pack (DFP) package. It supports a load capacitance of 50 pF and belongs to the TTL/H/L series, providing two sets of simultaneous outputs with configurable options.

Feature Summary

• Positive edge triggered operation for reliable data capture
• Three-state output capability for bus sharing applications
• Configurable output structure allowing simultaneous access to two output sets

Applications

• High-speed digital data storage systems
• Parallel data transfer interfaces
• Industrial control logic circuits

Procurement Notes

Verify the manufacturer designation as Advanced Micro Devices or Xilinx depending on the production era. Confirm the 20-CFlatPack package type matches the required footprint. Ensure the 3-state output configuration aligns with system bus requirements. Check for RoHS compliance status as original versions may not meet current environmental standards.

Selection Notes

Select this component when a 4-bit parallel storage element with tri-state outputs is required. The wide operating temperature range suits industrial environments. Consider the TTL compatibility for legacy system integration. Verify pinout compatibility if replacing older variants in existing designs.
