85507012A

Overview

The Texas Instruments 85507012A is an octal D-type edge-triggered flip-flop featuring three-state outputs. It is housed in a 20-pin LCCC package with dimensions of 8.89 mm length. The device operates within a temperature range of -55 °C to 125 °C and has a load capacitance of 50 pF. It belongs to the ALS logic series and functions as a single-element bus interface component.

Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops
• Three-state output capability for efficient bus interfacing
• Industrial temperature rating supporting operation from -55 °C to 125 °C

Applications

• Bus interface systems requiring high-density storage
• Digital data acquisition circuits
• Industrial control logic interfaces

Procurement Notes

Verify the specific manufacturer source, as the part number may appear under legacy or alternative branding. Confirm the package variant matches the required 20-pin LCCC footprint. Ensure the revision level aligns with your design specifications, as older logic families may have discontinued manufacturing lines. Check for compliance with current environmental regulations regarding halogen content.

Selection Notes

Select this component when an octal register with tri-state outputs is required for parallel data handling. The ALS series offers a balance of speed and power consumption suitable for general-purpose digital logic. Consider the 20-pin LCCC package constraints for PCB layout and thermal management during the design phase.

Part Context

This component belongs to the Texas Instruments ALS (Advanced Low-power Schottky) logic family. It serves as a fundamental building block for sequential logic circuits. The octal structure allows for the storage of multiple bits simultaneously, making it distinct from single-bit flip-flops in terms of integration density.

Replacement Considerations

Consult official substitution guides for compatible octal D-type flip-flops with three-state outputs. Verify pin compatibility and electrical characteristics before replacing.
