Dual-inverting, Independent Enable Function for Each Driver dual-noninvertering, and complementary outputs are Output standard logic options offered. Low Shoot-Through/Cross-Conduction Current in Output Stage The MCP14E3/MCP14E4/MCP14E5 drivers are capable of operating from a 4.5V to 18V single power Wide Input Supply Voltage Operating Range: supply and can easily charge and discharge 2200 pF - 4.5V to 18V gate capacitance in under 15 ns (typical). They provide High Capacitive Load Drive Capability: low impedance in both the ON and OFF states to - 2200 pF in 15 ns (typical) ensure the MOSFETs intended state will not be - 5600 pF in 26 ns (typical) affected, even by large transients. The MCP14E3/ MCP14E4/MCP14E5 inputs may be driven directly Short Delay Times: 50 ns (typical) from either TTL or CMOS (2.4V to 18V). Latch-Up Protected: Will Withstand 1.5A Reverse Current Additional control of the MCP14E3/MCP14E4/ Logic Input Will Withstand Negative Swing Up To MCP14E5 outputs is allowed by the use of separate enable functions. The ENB A and ENB B pins are 5V active high and are internally pulled up to V . The pins Space-Saving Packages: DD maybe left floating for standard operation. - 8-Lead 6x5 DFN, PDIP, SOIC The MCP14E3/MCP14E4/MCP14E5 dual-output 4.0A driver family is offered in both surface-mount and pin- Applications through-hole packages with a -40C to +125C Switch Mode Power Supplies temperature rating. The low thermal resistance of the thermally enhanced DFN package allows for greater Pulse Transformer Drive power dissipation capability for driving heavier Line Drivers capacitive or resistive loads. Motor and Solenoid Drive 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.
