MD1211 High Speed, Dual MOSFET Driver Features ►► ►► ►► ►► ►► ►► ►► ►► 10ns average rise and fall time with 1000pF load 2.0A peak output source/sink current 1.8 to 5.0V input CMOS compatible 4.5 to 13V total supply voltage Dual matched channels Reduced clock skew Low input capacitance Green packaging 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 highspeed input stage of the MD1211 can operate from 1.8 to 5.0V logic interface with an optimum operating input signal range of 1.8 to 3.3V. The level translator uses a proprietary circuit, which provides DC coupling together with high-speed operation.
