The TC7WB125FK is a low on-resistance, high-speed CMOS 2-bit bus switch from Toshiba. It features a minimal propagation delay while maintaining the low power dissipation of CMOS. When the output enable (OE) is at a low level, the switch is on; when it is at a 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 that provides fast, low‑loss connections between two bus lines. When the output‑enable (OE) pin is low the switch conducts, and when OE is high the switch is off. All inputs include protection circuits against static discharge.
Key specifications include a typical operating voltage of 4.5‑5.5 V, a propagation delay of 0.25 ns, and an on‑resistance of about 5 Ω. 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.
