General Description  
• 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 25mV of ground or positive supply.  
• ESD Protected: 2kV  
Applications  
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.  
• Switch Mode Power Supplies  
• Pulse Transformer Drive  
• Clock Line Driver  
• Coax Cable Driver  
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 high-frequency switch-mode power supply  
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.
