TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7SBL385FU
Single Low-Voltage Bus Switch
The TC7SBL385FU is a low on-resistance, high-speed CMOS 1-bit bus switch with low voltage operation. The low on resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as just 1-bit low-impedance switch with output-enable (OE) input. When OE is high, the switch is on and data can flow from port A to port B, or vice versa. When OE is low, the switch is open and a high-impedance state exists between the two ports. P-MOS and N-MOS channel block also allows that the device is suitable for analog signal transmission. All inputs are equipped with protection circuits against static discharge.
