Space-saving 8-Pin 6x5 DFN Package

General Description

The TC4423/TC4424/TC4425 devices are a family of3A, dual-output buffers/MOSFET drivers. Pin compati-ble with the TC1426/27/28, TC4426/27/28 andTC4426A/27A/28A dual 1.5A driver families, theTC4423/24/25 family has an increased latch-up currentrating of 1.5A, making them even more robust foroperation in harsh electrical environments.

As MOSFET drivers, the TC4423/TC4424/TC4425 caneasily charge 1800pF gate capacitance in under35nsec, providing low enough impedances in both theon and off states to ensure the MOSFET's intendedstate will not be affected, even by large transients.The TC4423/TC4424/TC4425 inputs may be drivendirectly from either TTL or CMOS (2.4V to 18V). Inaddition, the 300mV of built-in hysteresis providesnoise immunity and allows the device to be driven fromslowly rising or falling waveforms.
