... MAX5078A/ MAX5078B ideal for high-frequency and high-power circuits. The MAX5078A/MAX5078B operate from 15V single power supply and consume 40µA (typ) of supply current when not switching. These devices have an internal logic circuitry that prevents shoot-through during output state changes to minimize the operating current at a high switching frequency ...
