Ground any unused driver input. TC426/7/8-7 10/11/96 GENERAL DESCRIPTION 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 25 mV 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 volt- age. Input current is a low 1 µA, making direct interface to CMOS/bipolar switch-mode power supply control ICs pos- sible, 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 bipo- lar DS0026 device. This is important in DC-to-DC con- verter applications with power efficiency constraints and high-frequency switch-mode power supply applications. Qui- escent 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.
