Frequently Asked Questions
What voltage levels does the SN74CB3Q3306APWG support for bus switching?
The SN74CB3Q3306APWG is designed to switch bus signals at 2.5V and 3.3V supply and logic levels. It also features 5V-tolerant I/O pins allowing safe connection to 5V signal sources, making it versatile for mixed-voltage board designs combining 3.3V and 5V logic components.
What are the propagation delay and on-resistance characteristics of the SN74CB3Q3306APWG?
The SN74CB3Q3306APWG is a FET (MOSFET) bus switch that provides near-zero propagation delay because it operates as a direct resistance element rather than a regenerative logic gate. Its low on-resistance minimizes signal attenuation and timing skew, enabling use in high-speed memory and processor bus interconnects.
How many channels does the SN74CB3Q3306APWG have and how are they controlled?
The SN74CB3Q3306APWG contains two independent bus switch channels, each with an individual output enable (OE) control input. When OE is active (high), the corresponding switch channel closes and conducts; when OE is inactive (low), the channel opens and the I/O port becomes high-impedance, isolating the bus segment.
What package is the SN74CB3Q3306APWG available in?
The SN74CB3Q3306APWG is housed in a TSSOP (Thin Shrink Small Outline Package) surface-mount package. This thin, compact package is well-suited for high-density PCB designs in portable computing, servers, and networking equipment where board real estate is limited.
