Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package marking matches SSOP-16 specifications. Check datasheet revisions for any updates to electrical characteristics or pinout definitions. Ensure environmental compliance documentation aligns with project requirements prior to integration.

Selection Notes

Select this component when dual independent JK flip-flops are required in a compact surface-mount package. The HCT series ensures voltage level compatibility with TTL-driven systems. Consider the asynchronous control features for designs needing immediate output overrides without clock dependency. Evaluate thermal and mechanical constraints associated with the SSOP-16 footprint.

Part Context

This part belongs to the widely adopted 74HCT logic family, designed for seamless integration into mixed-voltage environments. The 74HCT112 specifically addresses applications requiring two independent bistable memory elements. Its pin-out remains compatible with legacy LSTTL designs, facilitating straightforward upgrades from older discrete or bipolar technologies to modern CMOS solutions.

Replacement Considerations

Public confirmed substitute part numbers include 74HCT112D and 74HCT112PW. These variants maintain identical logical functionality and pin configuration while differing primarily in package type or manufacturing origin suffixes.
