Low Voltage / Low Power 4-Bit Dual Supply Bus Switch
The TC7QPB9306FK and TC7QPB9307FK are CMOS 4-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.
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:TC7QPB9306FK, OE :TC7QPB9307FK) input is
common for all the 4-bits of the data lines; thus these device are used as a
single 4-bits bus switch. For the TC7QPB9306FK, Output Enable (OE) is
active-High: When OE is High, the switch is on; when Low, the switch is off.
For the TC7QPB9307FK, Output Enable ( OE ) is active-Low: When OE is
Low, the switch is on; when High, the switch is off.
The TC7QPB9306FK and TC7QPB9307FK 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.
