The TC7WB125FK is a low-on-resistance, high-speed CMOS 2-bit bus switch from Toshiba Corporation. It provides connections or disconnections with minimal propagation delay while maintaining low power dissipation, which is the characteristic of CMOS. When output enable (OE) is at low level, the switch is on; when at high level, the switch is off. All inputs are equipped with protector circuits to protect the device from static discharge.
The TC7WB125FK is a CMOS dual‑bus switch designed for fast, low‑power signal routing. It features a typical on‑resistance of 5 Ω, propagation delay of 0.25 ns (max), and operates from a 4.5‑5.5 V supply. All inputs include ESD protection up to +2000 V (human‑body model).
The datasheet provides absolute maximum ratings, operating ranges, DC and AC electrical characteristics, package dimensions (SSOP8‑P‑0.50A, 0.01 g), and usage restrictions for safety‑critical applications.
