General Description
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
with a 2-input logic gate for added flexibility. Placing four high-
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.
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
driver capable of high peak currents, rail-to-rail voltage swings,
and fast switching times. For example, heavily loaded clock
lines, coaxial cables, and piezoelectric transducers can all be

driven easily with MIC446X series drivers. The only limitation
on loading is that total power dissipation in the IC must be
kept within the power dissipation limits of the package.
The MIC446X series drivers are built using a BCD process.
They will not latch under any conditions within their power and
voltage ratings. They are not subject to damage when up to
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.
