The TC426/TC427/TC428 are dual CMOS high-speeddrivers. A TTL/CMOS input voltage level is translatedinto a rail-to-rail output voltage level swing. The CMOSoutput is within 25 mV of ground or posiTIve supply.The low-impedance, high-current driver outputs swinga 1000 pF load 18V in 30 nsec. The unique current andvoltage drive qualiTIes make the TC426/TC427/TC428ideal power MOSFET drivers, line drivers, and DC-to-DC converter building blocks.Input logic signals may equal the power supply voltage.Input current is a low 1 μA, making direct interfaceto CMOS/bipolar switch-mode power supply controlICs possible, as well as open-collector analogcomparators.Quiescent power supply current is 8 mA maximum. TheTC426 requires 1/5 the current of the pin-compaTIblebipolar DS0026 device. This is important in DC-to-DCconverter applicaTIons with power efficiency constraintsand high-frequency switch-mode power supplyapplications. Quiescent current is typically 6 mA whendriving a 1000 pF load 18V at 100 kHz.The inverting TC426 driver is pin-compatible with thebipolar DS0026 and MMH0026 devices. The TC427 isnoninverting; the TC428 contains an inverting and noninvertingdriver.Other pin compatible driver families are the TC1426/TC1427/TC1428, TC4426/TC4427/TC4428 andTC4426A/TC4427A/TC4428A.
