... They can accept, without either damage or logic upset half an amp of reverse current (either polarity) forced back into their outputs. The MIC4123/4124/4125 series drivers are easier to use, more flexible in operation, and more forgiving than other CMOS or bipolar drivers currently available. Their BiCMOS/DMOS construction dissipates minimum power and provides rail-to- rail voltage swings ...

... MIC4123/4124/4125 Application Information Although the MIC4123/24/25 drivers have been specifically constructed to operate reliably under any practical circum- stances, there are nonetheless details of usage which will provide better operation of the device. Supply Bypassing Charging and discharging large capacitive loads quickly requires large currents. For example, charging 2000pF from volts in 20ns requires a constant current of 1 ...
