Product details

100112DCQR — Inverter/Buffer, 100K Series

The 100112DCQR is an inverter/buffer from the 100K series, a logic family known for its high-speed ECL (Emitter-Coupled Logic) operation. This part is designed for signal inversion and buffering in systems where propagation delay and edge rates are critical — think clock distribution, data-path conditioning, or level translation between ECL and other logic families. The 100K series typically operates from a -4.5 V or -5.2 V supply rail, so the board design needs to account for negative-rail routing rather than the more common +3.3 V or +5 V.

That said, the 100K series is a mature logic family — not a new design-in candidate for most projects.

For a repair bench or low-volume production run that is fine, but if your pick-and-place line expects tape, factor in the hand-loading or a tube-to-tape conversion step.

Frequently asked questions

What is the closest functional equivalent to 100112DCQR?

The DM7098J is a peer part from the same functional class — an inverter/buffer in the 100K series, also in Bulk package. It is a direct functional alternative for cross-referencing or second-sourcing, though pinout and electrical characteristics should be verified against the respective datasheets for your specific application.
