TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7SB384FU
Single Bus Switch
The TC7SB384FU provides single bit of high-speed TTL-compatible switching. 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 low, the switch is on and data can flow from port A to port B, or vice versa. When OE is high, the switch is open and a high-impedance state exists between the two ports. All inputs are equipped with protection circuits against static discharge.

Quiescent supply current
Note1: Typical values are at VCC = 5 V and Ta = 25°C. Note2: Measured by the voltage drop between A and B pins at the indicated current through the switch. On resistance is determined by the lower of the voltages on the two (A or B) pins.
