General Description
The Supertex MD1211 is a high speed, dual MOSFET driver.
It is designed to drive high voltage N- and P-channel MOSFET
transistors for medical ultrasound and other applications
requiring a high output current for a capacitive load. The
high-speed input stage of the MD1211 can operate from 1.2
to 5.0 volt logic interface with an optimum operating input
signal range of 1.8 to 3.3 volts. The level translator uses a
proprietary circuit, which provides DC coupling together with
high-speed operation.

Absolute Maximum Ratings are those values beyond which damage to the
device may occur. Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level may affect
device reliability. All voltages are referenced to device ground.
