General Description

The TC4423M/TC4424M/TC4425M devices are a

family of 3A, dual output buffers/MOSFET drivers. Pin-

compatible

with

both

the

TC4426M/TC4427M/

TC4428M and TC4426AM/4427AM/4428AM families

(dual 1.5A drivers), the TC4423M/TC4424M/TC4425M

family has an increased latch-up current rating of 1.5A,

making them even more robust for operation in harsh

electrical environments.

As

MOSFET

drivers,

the

TC4423M/TC4424M/

TC4425M can easily charge 1800 pF gate capacitance

in

under

35 nsec,

while

providing

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.

The TC4423M/TC4424M/TC4425M inputs may be

driven directly from either TTL or CMOS (2.4V to 18V).

In addition, 300 mV of hysteresis is built-in to provide

noise immunity and to allow the device to be driven

from slowly rising or falling waveforms.
