| MD1211 New Release High Speed, Dual MOSFET Driver Features 10ns average rise and fall time with 1000pF load 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. 2.0A peak output source/sink current 1.2V to 5.0V input CMOS compatible 4.5V to 13V total supply voltage Dual matched channels Reduced clock skew Low input capacitance Green packaging Applications Medical ultrasound imaging Piezoelectric transducer drivers Nondestructive evaluation PIN diode driver High speed level translator Clock/line drivers Typical Application Circuit VDD 0.47F MD1211 VLL +100V INA Level Shifter OUTA 1F 10nF To Piezoelectric Transducer -100V INB Level Shifter 10nF OUTB Supertex TC6320TG GND 1F NR011806 1 MD1211 Ordering Information Package Option DEVICE 8-Pin SOIC MD1211 MD1211LG-G -G indicates package is RoHS compliant (`Green') Absolute Maximum Ratings Parameter Logic Supply Voltage Main Supply Voltage Logic Input Levels Maximum Junction Temperature Storage Temperature Value -0.5V to +5.5V -0.5V to +13.5V -0.5V to VLL+0.5V +125C -65C to 150C 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.
