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 1000 pF load 18V in 30 nsec. 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 1 μA, making direct interface
to CMOS/bipolar switch-mode power supply control
ICs possible, as well as open-collector analog

Range
Quiescent power supply current is 8 mA maximum. The
