Frequently Asked Questions
What voltage levels does the SN74CB3Q3306APWR support?
The SN74CB3Q3306APWR supports both 2.5V and 3.3V supply voltages, making it suitable for mixed-voltage system designs. It features a low ON-resistance FET switch that maintains signal integrity across both voltage domains, with a load capacitance rating of 50pF.
How does the enable control work on the SN74CB3Q3306APWR?
The SN74CB3Q3306APWR uses an active-low enable (OE#) control pin. When the enable pin is driven low, the bus switch is turned on and the signal path is connected. When driven high, the switch is disabled, isolating the bus. This unidirectional control simplifies integration with standard digital logic.
What are typical applications for the SN74CB3Q3306APWR?
Typical applications include low-voltage bus switching in smartphones, tablets, notebooks, and IoT devices. It is commonly used for memory interface routing, processor-to-peripheral multiplexing, and signal isolation in battery-powered portable electronics where 2.5V or 3.3V operation is required.
What package does the SN74CB3Q3306APWR come in and where can I buy it?
The SN74CB3Q3306APWR is available in an 8-pin TSSOP (R-PDSO-G8) small outline package. It is priced from approximately $0.19 per unit and is available with worldwide shipping through authorized distributors and online electronics component suppliers.
