TheMIC4467/8/9familyof4-outputCMOSbuffer/driversisan
expansion from the earlier single- and dual-output drivers, to
whichtheyarefunctionallycloselyrelated. Becausepackage
pin count permitted it, each driver has been equipped with a
2-inputlogicgateforaddedflexibility.Placingfourhigh-power
drivers in a single package also improves system reliability
and reduces total system cost. In some applications, one of
these drivers can replace not only two packages of single-
input drivers, but some of the associated logic as well.
Although primarily intended for driving power MOSFETs,
and similar highly capacitive loads, these drivers are equally
well suited to driving any other load (capacitive, resistive, or
inductive), which requires a high-efficiency, low-impedance
drivercapableofhighpeakcurrents,rail-to-railvoltageswings,
and fast switching times. For example, heavily loaded clock
lines, coaxialcables, andpiezoelectrictransducerscanallbe
driven easily with MIC446X series drivers. The only limitation

line. They can accept up to half an amp of inductive kickback
current (either polarity) into their outputs without damage or
logic upset.
The MIC446X series drivers are built using a BCD process.
They will not latch under any conditions within their power
