■ TTL/CMOS Input Compatible  
■ Available in Inverting and Noninverting  
Configurations  
■ Wide Operating Supply Voltage ............ 4.5V to 18V  
■ Current Consumption  
— Inputs Low .................................................. 0.4mA  
— Inputs High .................................................... 8mA  
■ Single Supply Operation  
■ Low Output Impedance ........................................ 6Ω  
■ Pinout Equivalent of DS0026 and MMH0026  
■ Latch-Up Resistant: Withstands > 500mA  
Reverse Current  
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 1µA, 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-frequencyswitch-modepowersupply applications. Qui-  
escent current is typically 6mA when driving a 1000pF load  
18V at 100kHz.  
■ ESD Protected ......................................................2kV  
PIN CONFIGURATIONS (DIP and SOIC)  
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.
