TOSHIBA TC7SBD385AFU

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.

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, Ta = 25°C.
Note 2: It recommends that this device uses Pull-up resistance when adding and using resistance for
an output terminal. 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.
