1. Functional Description
• Low-Voltage, Low-Power 2-Bit Dual-Supply Bus Switch
2. General
The TC7WPB8306L8X and TC7WPB8307L8X are CMOS 2-bit dual-supply bus switches that can provide an
interface between two nodes at different voltage levels. These devices can be connected to two independent power
supplies. VCCA supports 1.8-V, 2.5-V and 3.3-V power supplies, whereas VCCB supports 2.5-V, 3.3-V and 5.0 V
power supplies.
Each An terminal has an internal pull-up resistor to VCCA, and each Bn terminal has an internal pull-up resistor
to VCCB. And each I/O terminal has a signal level detection circuit which speeds up the low-to-high transition.
The Output Enable (OE: TC7WPB8307L8X, OE: TC7WPB8306L8X) input is common for all the two-bits of the
data lines; thus these device are used as a single two-bits bus switch. For the TC7WPB8306L8X, Output Enable
(OE) is active-High: When OE is High, the switch is on; when Low, the switch is off. For the TC7WPB8307L8X,
Output Enable (OE) is active-Low: When OE is Low, the switch is on; when High, the switch is off. All inputs
and outputs of the TC7WPB8306L8X and TC7WPB8307L8X can tolerate overvoltage conditions up to 5.5 V. The
channels consist of n-type MOSFETs.
All the inputs provide protection against electrostatic discharge.

7. Block Diagram
One-shot driver circuits (RA1, RB1, RA2 and RB2) of the TC7WPB8306L8X and TC7WPB8307L8X detect either
a rising or falling edge on the A or B port. During the rise time, the RA1 and RB1 transistors are turned on for
a certain period to speed up a transition from Low to High. Likewise, during the fall time, the RA2 and RB2
transistors are turned on to speed up a transition from High to Low.

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).
