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.
