Built using reliable, low power CMOS processes
Latchproof. Withstands 500mA Inductive Kickback
3 Input Logic Choices
Symmetrical Rise and Fall Times .......................... 25ns
Short, Equal Delay Times ...................................... 75ns
High Peak Output Current ...................................... 1.2A
Wide Operating Range ..................................4.5 to 18V
Low Equivalent Input Capacitance (typ) .................. 6pF
The MIC4467/8/9 family of 4-output CMOS buffer/drivers is
an expansion from the earlier single- and dual-output drivers,
to which they are functionally closely related. Because pack-
age pin count permitted it, each driver has been equipped
witha2-inputlogicgateforaddedflexibility.Placingfourhigh-
power drivers in a single package also improves system
reliability and reduces total system cost. In some applica-
tions, one of these drivers can replace not only two packages
of single-input drivers, but some of the associated logic as
well.

AlthoughprimarilyintendedfordrivingpowerMOSFETs, 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

on loading is that total power dissipation in the IC must be
kept within the power dissipation limits of the package.

5V of noise spiking (either polarity) occurs on the ground 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.
