General Description

The MCP14A0051/2 devices are high-speed MOSFET

drivers that are capable of providing up to 0.5A of peak

current while operating from a single 4.5V to 18V

supply. The inverting (MCP14A0051) or noninverting

(MCP14A0052) single-channel output is directly

controlled from either TTL or CMOS (2V to 18V) logic.

These devices also feature low shoot-through current,

matched rise and fall times and short propagation

delays, which make them ideal for high switching

frequency applications.

The MCP14A0051/2 family of devices offers enhanced

control with enable functionality. The active-high

Enable (EN) pin can be driven low to drive the output of

the MCP14A0051/2 low, regardless of the status of the

Input (IN) pin. An integrated pull-up resistor allows the

user to leave the Enable pin floating for standard

operation.

Additionally, the MCP14A0051/2 devices feature separate

ground pins (AGND and GND), allowing greater

noise isolation between the level-sensitive Input/

Enable pins and the fast, high-current transitions of the

push-pull output stage.

These devices are highly latch-up resistant under any

condition within their power and voltage ratings. They

can accept up to 500 mA of reverse current being

forced back into their outputs without damage or logic

upset. All terminals are fully protected against

Electrostatic Discharge (ESD) up to 1.75 kV (HBM) and 100V (MM).
