Maxim Integrated MAX800L
The MAX691A/MAX693A/MAX800L/MAX800M microprocessor (μP) supervisory circuits are pin-compatible upgrades to the MAX691, MAX693, and MAX695. They improve performance with 30μA supply current, 200ms typ reset active delay on power-up, and 6ns chip-enable propagation delay. The MAX691A/ MAX800L have a 4.65V typical reset-threshold voltage, and the MAX693A/MAX800Ms’ reset threshold is 4.4V typical.| Part No. | MAX800L |
