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 package
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 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
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.
