The TC7WBD126FK is a low on-resistance, high-speed CMOS 2-bit bus switch. It has the low power dissipation feature of CMOS. When the output enable (OE) is high, the switch is on; when it is low, the switch is off. The internal diode allows the signal level to shift from 5V to 3.3V.
The TC7WBD126FK is a CMOS dual‑bus switch that provides low on‑resistance and high‑speed operation while shifting signal levels from 5 V to 3.3 V. It features protected inputs, ESD robustness, and a compact SSOP8‑P‑0.50A package.
Typical specifications include a 4.5‑5.5 V operating voltage, 0.25 ns propagation delay, 5 Ω typical on‑resistance, and a power dissipation of 200 mW. The device is rated for continuous channel current of 128 mA and operates over a storage temperature range of –65 °C to 150 °C.
