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 non-inverting
(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 offer enhanced
control with Enable functionality. The active-high
Enable pin can be driven low to drive the output of the
MCP14A0051/2 low regardless of the status of the
Input pin. An integrated pull-up resistor allows the user
to leave the Enable pin floating for standard operation.
Additionally, the MCP14A0051/2 devices feature sepa-
rate ground pins (A_GND 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).
