TC7SB66FU TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TC7SB66FU Single Bus Switch The TC7SB66FU is a low on-resistance, high-speed CMOS 1-bit bus switch. 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. Weight: 0.006 g (typ.)
