Low Voltage / Low Power 1-Bit Dual Supply Bus Switch
The TC7SPB9306 and TC7SPB9307 are CMOS 1-bit
dual-supply bus switches that can provide an interface between
TC7SPB9306TU,TC7SPB9307TU
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.
Bidirectional level-shifting is possible by simply adding
external pull-up resistors between the A/B data lines and the
VCCA/VCCB supplies. There is no restriction on the relative
magnitude of the A and B voltages; both the A and B data lines
can be pulled up to arbitrary power supplies.
Weight: 7 mg (typ.)
The enable signal can be used to disable the device so that the
buses are effectively isolated.
For the TC7SPB9306, Output Enable (OE) is active-High: When OE is High, the switch is on; when Low, the
switch is off. For the TC7SPB9307, Output Enable ( OE ) is active-Low: When OE is Low, the switch is on; when
High, the switch is off.
The TC7SPB9306 and TC7SP9307 supports power-down protection at the OE ,OE input, with OE ,OE being
5.5-V tolerant.
The channels consist of n-type MOSFETs.
All the inputs provide protection against electrostatic discharge.
