The TC4427A is a dual non-inverting high-speed MOSFET driver capable of sourcing or sinking 1.5A peak current. It operates over a supply voltage range of 4.5V to 18V and can drive 1000pF loads with a typical rise and fall time of 25ns. Propagation delay is typically 30ns, with matched rise, fall, and delay times across both channels. The device features a typical output impedance of 7Ω, low Quiescent current of 1mA with a logic high input and 100µA with a logic low input, and is protected against ESD up to 2kV. It is available in 8-pin MSOP and 8-pin 6x5 DFN-S packages with an exposed thermal pad.
The TC4426A/4427A/4428A 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 TC4426A/4427A/4428A can easily switch 1000pF 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.
