TC7SB384FU
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.
Weight: 0.006 g (typ.)

Absolute Maximum Ratings (Note)
Characteristics Power supply range DC input voltage DC switch voltage Input diode current Continuous channel current Power dissipation DC VCC/GND current Storage temperature Symbol VCC VIN VS IIK IS PD ICC/IGND Tstg Rating -0.5~7.0 -0.5~7.0 -0.5~7.0 -50 128 200 100 -65~150 Unit V V V mA mA mW mA C
Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Note 1: Typical values are at VCC = 5 V and Ta = 25C. Note 2: 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.
