Frequently Asked Questions
What is the bit width of the SN74CBTS16211DLG4?
The SN74CBTS16211DLG4 is a 12-bit bus switch, providing 12 independent switch channels in a single package. Each channel is independently controlled by the output enable (OE) signal, which is active-low, allowing the entire 12-bit bus to be connected or isolated from the system bus simultaneously.
What is the propagation delay of the SN74CBTS16211DLG4?
As a CBT-family bus switch, the SN74CBTS16211DLG4 provides near-zero propagation delay because it uses MOSFETs as pass-gate switches rather than logic gates. This makes it ideal for transparent bus connections where signal integrity and timing must be preserved across high-frequency data paths.
What package does the SN74CBTS16211DLG4 use?
The SN74CBTS16211DLG4 is available in a 56-pin SSOP (Shrink Small Outline Package), a surface-mount package with a fine pitch of 0.635mm designed for compact PCB layouts. This package is compatible with automated assembly processes and is suitable for high-density digital system designs.
Is the SN74CBTS16211DLG4 RoHS compliant?
Yes, the SN74CBTS16211DLG4 carries the G4 suffix indicating it is RoHS compliant and lead-free, conforming to JESD-609 e4 environmental coding. This ensures the component meets worldwide hazardous substance regulations including EU RoHS directives for commercial and industrial products.
