100155DC

National Semiconductor 100155DC is listed under the Gates and Inverters - Multi-Function, Configurable category and is commonly used when correctness, reliability, and qualification repeatability matter. Designers use them to bridge voltage domains, protect I/O, and keep edges and thresholds well-behaved on shared buses. In many systems, careful use of interface logic reduces integration risk by making timing and signal integrity easier to validate. In test fixtures, gating simplifies stimulus routing so measurement steps remain repeatable across cycles and operators. In control and timing paths, simple gating enforces sequencing and interlocks where deterministic hardware behavior is preferred over firmware. Overall, it strengthens system robustness by aligning electrical, thermal, and mechanical constraints with real deployment conditions.
