The TC426 is a dual inverting high-speed CMOS MOSFET driver with 1.5A peak output current and 6Ω output impedance, designed to switch a 1000 pF load 18V in 30 ns. It operates from a 4.5V to 18V single supply, with TTL/CMOS input compatibility and input current less than 1 μA. Quiescent supply current is 8 mA maximum when inputs are high, and 0.4 mA when low. The device is available in 8-pin PDIP, SOIC, and CERDIP packages and is latch-up resistant with 2 kV ESD protection. It is pin-compatible with the DS0026 and MMH0026 bipolar drivers.
The TC426/TC427/TC428 are 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 25mV of ground or positive supply. The low impedance, high-current driver outputs swing a 1000pF load 18V in 30nsec. The unique current and voltage drive qualities make the TC426/TC427/TC428 ideal 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 1A, 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 8mA maximum. The TC426 requires 1/5 the current of the pin-compatible bipolar DS0026 device. This is important in DC-to-DC converter applications with power efficiency constraints and high-frequency switch-mode power supply applications. Quiescent current is typically 6mA when driving a 1000pF load 18V at 100kHz. The inverting TC426 driver is pin-compatible with the bipolar DS0026 and MMH0026 devices. The TC427 is noninverting; the TC428 contains an inverting and non-inverting driver. Other pin compatible driver families are the TC1426/27/28, TC4426/27/28, and TC4426A/27A/28A.
