GENERAL DESCRIPTION
The TC4426/4427/4428 are improved versions of the
earlier TC426/427/428 family of buffer/drivers (with which
they are pin compatible). They will not latch up under any
conditions within their power and voltage ratings. They are
not subject to damage when up to 5V of noise spiking (of
either polarity) occurs on the ground pin. They can accept,
without damage or logic upset, up to 500 mA of reverse
current (of either polarity) being forced back into their
outputs. All terminals are fully protected against up to 4kV of
electrostatic discharge.
As MOSFET drivers, the TC4426/4427/4428 can easily
switch 1000pF gate capacitances in under 30nsec, and
provide low enough impedances in both the ON and OFF
states to ensure the MOSFET's intended state will not be
affected, even by large transients.
Other compatible drivers are the TC4426A/27A/28A.
These drivers have matched input to output leading edge
and falling edge delays, tD1 and tD2, for processing short
duration pulses in the 25 nsec range. They are pin compat-
ible with the TC4426/27/28.

*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under "Absolute Maximum Ratings" may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operation sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
