TC7WBD125AFK is a low on-resistance, high-speed CMOS 2-bit bus switch from Toshiba. This bus switch allows connections or disconnections to be made with minimal propagation delay while maintaining Low power dissipation which is the feature of CMOS. When output enable (OE) is at low level, the switch is on; when at high level, the switch is off. The device is enable to realize the shift of signal level from 5 V to 3.3 V. All inputs are equipped with protector circuits to protect the device from static discharge.
The TC7WBD125AFK is a low‑on‑resistance, high‑speed CMOS dual‑bus switch that shifts signal levels from 5 V to 3.3 V. It features TTL‑level inputs, ESD protection, and a typical on‑resistance of 5 Ω.
Key specifications include an operating voltage of 4.5‑5.5 V, propagation delay of 0.32 ns (max), and a power‑down current of 10 pA (max). The device is supplied in an SSOP8‑P‑0.50A package and is intended for general electronics applications such as computers, office equipment, and industrial robotics.
