TC427EOA

The TC427 is a dual CMOS high-speed drivers. A TTL/CMOS input voltage level is translated into a rail-to-rail output voltage level swing. The CMOS output is within 25 mV of ground or positive supply. The low-impedance, high-current driver outputs swing a 1000 pF load 18V in 30 nsec. The unique current and voltage drive qualities make the TC427 ideal power MOSFET drivers, line drivers, and DC-toDC converter building blocks. Input logic signals may equal the power supply voltage. Input current is a low 1 µA, making direct interface to CMOS/bipolar switch-mode power supply control ICs possible, as well as open-collector analog comparators Quiescent power supply current is 8 mA maximum. TheThis is important in DC-to-DC converter applications with power efficiency constraints and high-frequency applications. Quiescent current is typically 6 mA when switch-mode power supply driving a 1000 pF load 18V at 100 kHz The TC427 is noninverting driver.
