TC7SBD385AFU TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7SBD385AFU Single Bus Switch with Level Shifting The TC7SBD385AFU 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 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. The device is enable to realize the shift of signal level from 5 V to 3.3 V. All inputs are equipped with protection circuits against static discharge. Weight: 0.006 g (typ.)

Since it couses to drop a VOH voltage level when using Pull-down resistance for an output terminal. Note 3: 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.
