-With Logic �0’ Input – 350 µA (Max) Low Output Impedance: 3.5 (typ) Latch-Up Protected: Will Withstand 1.5A Reverse
Current Logic Input Will Withstand Negative Swing Up To
5V ESD Protected: 4 kV Pin compatible with the TC1426/TC1427/TC1428,
TC4426/TC4427/TC4428 and TC4426A/
TC4427A/TC4428A devices. Space-saving 8-Pin 6x5 DFN Package The TC4423/TC4424/TC4425 devices are a family of
3A, dual-output buffers/MOSFET drivers. Pin compatible with the TC1426/27/28, TC4426/27/28 and
TC4426A/27A/28A dual 1.5A driver families, the
TC4423/24/25 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 TC4423/TC4424/TC4425 can
easily charge 1800 pF gate capacitance in under
35 nsec, 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 TC4423/TC4424/TC4425 inputs may be driven
directly from either TTL or CMOS (2.4V to 18V). In …

5V ESD Protected: 4 kV Pin-compatible with the TC4426M/TC4427M/
TC4428M and TC4426AM/TC4427AM/
TC4428AM devices Wide Operating Temperature Range:
-55В°C to +125В°C See TC4423/TC4424/TC4425 Data Sheet
(DS21421) for additional temperature range and
packaging offerings The TC4423M/TC4424M/TC4425M devices are a
family of 3A, dual output buffers/MOSFET drivers. Pincompatible 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. 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 …
