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 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 1µA, 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
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/
TC1427/TC1428,
TC4426A/TC4427A/TC4428A.
