Product Overview
The National Semiconductor MM80C98N is a 3-state hex inverting buffer constructed with monolithic CMOS technology. It features split enable controls, allowing either 2-line or 4-line control over high-impedance output states for efficient bus-oriented logic designs. Built in a standard 16-pin through-hole dual in-line package, it operates across a wide supply voltage range from 3.0V to 15V with diode clamp protection on all inputs.

Frequently Asked Questions
What is the pin count and package type?
This integrated circuit is housed in a standard 16-pin plastic DIP (through-hole) package.
How are the 3-state output enables controlled?
The six internal inverters are grouped under two separate active-low enable lines (2-line and 4-line) to place outputs into a high-impedance state.
Why buy a single piece instead of chasing a bulk surplus lot?
When you are troubleshooting a specific board failure or repairing a legacy build, you need the exact component shown, not a blind bag of surplus extras. You receive the specific National Semiconductor MM80C98N IC photographed here. Shipping is an $8 flat rate, free once the order passes $28, and orders leave our Idaho warehouse the same or next business day.
Vintage CMOS logic that stepped right out of working hardware, ready to drive the exact signal your legacy bus expects.
