The TC426/TC427/TC428 are three dual CMOS high-speed drivers that support TTL/CMOS input and output voltage between VDD-25mV and GND+25mV. The output current can reach 1.5A, and the output impedance is 6 ohms.
The TC426/TC427/TC428 family are dual CMOS high‑speed drivers that translate TTL/CMOS input levels to rail‑to‑rail output swings. They operate from a single supply of 4.5 V to 18 V and provide up to 1.5 A peak output current with low input current.
The document includes electrical characteristics, pin descriptions, application notes, and typical performance graphs. It also provides ordering information for various package types (SOIC, PDIP, CERDIP) and outlines recommended layout and grounding practices for optimal switching speed.
