TC7WPB9306FK, TC7WPB9307FK Low Voltage/Low Power 2-Bit Dual Supply Bus Switch
The TC7WPB9306 and TC7WPB9307 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 5.0V power supplies.
Bidirectional level-shifting is possible by simply adding
external pull-up resistors between the An/Bn data lines and the
VCCA / VCCB supplies. There is no restriction on the relative
magnitude of the An and Bn voltages; both the An and Bn data
lines can be pulled up to arbitrary power supplies.
The enable signal can be used to disable the device so that the
buses are effectively isolated.
The Output Enable ( OE :TC7WPB9307, OE:TC7WPB9306)
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
TC7WPB9306, Output Enable (OE) is active-High: When OE is
High, the switch is on; when Low, the switch is off. For the
TC7WPB9307, Output Enable ( OE ) is active-Low: When OE is
Low, the switch is on; when High, the switch is off.
The TC7WPB9306 and TC7WP9307 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.
