Overview
The LSF0102DC-Q100H, produced by Nexperia USA Inc., is a 2-channel bidirectional multi-voltage level translator designed for open-drain and push-pull applications. This device supports up to 100 MHz up translation and ≥100 MHz down translation at a capacitive load of ≤ 30 pF. It does not require a direction pin, minimizing system complexity. The LSF0102DC-Q100H is highly flexible, allowing different voltage translation levels on each channel, and is compatible with TTL levels due to its 5 V tolerant I/O pins.
