Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Off is
≤
0.8V and on is
≥
2.4V for the MIC2544-1 and MIC2548-1. Off is
≥
2.4V and on is
≤
0.8V for the MIC2544-2 and MIC2548-2. The
enable input has about 200mV of hysteresis.
