TC7QPB9307FK Datasheet Low Voltage / Low Power 4-bit Dual Supply Bus Switch

Manufacturer: Toshiba

Overview: TC7QPB9306FK, TC7QPB9307FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7QPB9306FK, TC7QPB9307FK 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. TC7QPB9306FK, TC7QPB9307FK Weight VSSOP14-P-0030-0.50 : 0.02 g (typ.
