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.
