The TC7WBD125AFK is a low on-resistance, high-speed CMOS 2-bit bus switch from Toshiba. This bus switch allows the 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 dual‑bus switch that provides low on‑resistance and high‑speed operation while shifting signal levels from 5 V to 3.3 V. When the output‑enable (OE) pin is low the switch is on, and it turns off when OE is high. All inputs include protection circuits against static discharge.
Key specifications include an operating voltage of 4.5‑5.5 V, typical on‑resistance of 5 Ω, propagation delay up to 0.32 ns, and ultra‑low power dissipation (10 pA). The device is supplied in an SSOP8‑P‑0.50A package and is rated for temperatures from –40 °C to 85 °C (operating) and –65 °C to 150 °C (storage).
