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 500mA 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 1000 pF 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 nanoseconds range. They are pin

compatible 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.
