This datasheet provides detailed information on the TC426/TC427/TC428 high current dual CMOS switch drivers. These drivers are ideal for high current applications such as switch mode power supplies, pulse transformer drive, clock line driver and coax cable driver.
The TC426/TC427/TC428 are dual CMOS high-speed drivers designed for high-speed switching applications such as switch mode power supplies, pulse transformer drive, and clock line driving. These devices translate TTL/CMOS input voltage levels into rail-to-rail output voltage swings within 25mV of ground or the positive supply.
Key features include a high peak output current of 1.5A capable of swinging a 1000pF load in 30 nanoseconds, low input current (1 µA), and wide operating supply voltage ranging from 4.5V to 18V. The family includes the TC426 (inverting), TC427 (non-inverting), and TC428 (complementary) configurations.
| Peak Output Current | 1.5A |
|---|---|
| Switching Time (Rise/Fall) | 30 nsec |
| Operating Supply Voltage | 4.5V to 18V |
| Input Current (Logic 0 or 1) | 1 µA |
