The TC7WB66FK is a low on-resistance, high-speed CMOS2-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 High level, the switch is on; when at Low level, the switch is off. P-MOS and N-MOS channel block means the device is suitable for analog signal transmission. All inputs are equipped with protector circuits to protect the device from static discharge.
The TC7WB66FK is a CMOS 2‑bit dual‑bus switch designed for fast, low‑power signal routing. It features a P‑MOS/N‑MOS channel structure, ESD‑protected inputs, and a compact SSOP8‑P‑0.50A package.
The datasheet provides electrical characteristics, absolute maximum ratings, pin assignments, and package dimensions, along with usage restrictions and reliability notes for designers.
