General Description
The MCP14E3/MCP14E4/MCP14E5 devices are a family of 4.0A buffers/MOSFET drivers. Dual-inverting, dual-noninvertering, and complementary outputs are standard logic options offered.
The MCP14E3/MCP14E4/MCP14E5 drivers are capable of operating from a 4.5V to 18V single power supply and can easily charge and discharge 2200 pF gate capacitance in under 15 ns (typical). They provide low impedance in both the ON and OFF states to ensure the MOSFET’s intended state will not be affected, even by large transients. The MCP14E3/ MCP14E4/MCP14E5 inputs may be driven directly from either TTL or CMOS (2.4V to 18V).
Additional control of the MCP14E3/MCP14E4/ MCP14E5 outputs is allowed by the use of separate enable functions. The ENB_A and ENB_B pins are active high and are internally pulled up to V maybe left floating for standard operation.
The MCP14E3/MCP14E4/MCP14E5 dual-output 4.0A driver family is offered in both surface-mount and pin­through-hole packages with a -40°C to +125°C temperature rating. The low thermal resistance of the thermally enhanced DFN package allows for greater power dissipation capability for driving heavier capacitive or resistive loads.
These devices are highly latch-up resistant 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
1.5A of reverse current being forced back into their outputs. All terminals are fully protect against Electrostatic Discharge (ESD) up to 4 kV.

In some graphs or tables, the data presented may be outside the specified operating range (e.g., outside specified power supply range) and therefore outside the warranted range.
