The TC4423A/TC4424A/TC4425A devices are a familyof dual-output 3A buffers/MOSFET drivers. Thesedevices are improved versions of the earlier TC4423/TC4424/TC4425 dual-output 3A driver family. Thisimproved version features higher peak output currentdrive capability, lower shoot-throught current, matchedrise/fall TImes and propagaTIon delay TImes. TheTC4423A/TC4424A/TC4425A devices are pincompaTIblewith the existing TC4423/TC4424/TC4425family. An 8-pin SOIC package option has been addedto the family. The 8-pin DFN package option offersincreased power dissipation capability for drivingheavier capacitive or resistive loads.The TC4423A/TC4424A/TC4425A MOSFET driverscan easily charge and discharge 1800 pF gatecapacitance in under 20 ns, provide low enoughimpedances in both the on and off states to ensure theMOSFET’s intended state will not be affected, even bylarge transients.The TC4423A/TC4424A/TC4425A inputs may bedriven directly from either TTL or CMOS (2.4V to 18V).In addition, the 300 mV of built-in hysteresis providesnoise immunity and allows the device to be driven fromslow rising or falling waveforms.The TC4423A/TC4424A/TC4425A dual-output 3AMOSFET driver family is offerd with a -40oC to +125oCtemperature rating, making it useful in any widetemperature range application.
