Frequently Asked Questions
What is the SN74CBT16211ADLG4 and what does it do?
The SN74CBT16211ADLG4 is a 3.3 V 24-bit bus switch IC from Texas Instruments. It provides bidirectional 12-bit dual-channel bus switching with near-zero propagation delay, making it ideal for high-speed data routing applications where signal integrity and low latency are critical.
What package and pin count does the SN74CBT16211ADLG4 use?
The SN74CBT16211ADLG4 comes in a 56-pin Small Outline IC (SOIC) package, designated JESD-30 code R-PDSO-G56. This surface-mount package is well-suited for space-constrained PCB designs requiring a high pin count bus switch.
How is the SN74CBT16211ADLG4 enabled or disabled?
The device uses active-low enable control signals to activate or deactivate each 12-bit bus switch channel independently. When the enable pin is pulled low, the corresponding channel conducts; when pulled high, the channel is in a high-impedance state, isolating the bus.
Is the SN74CBT16211ADLG4 RoHS compliant?
Yes, the SN74CBT16211ADLG4 is RoHS compliant as indicated by its JESD-609 code e4, which confirms the device is manufactured without restricted hazardous substances including lead, mercury, and cadmium.
What are typical applications for the SN74CBT16211ADLG4?
Typical applications include bus isolation and switching in memory interfaces, data communication systems, backplane interconnects, and any digital design where multiple bus masters need to share a common data bus. Its dual-channel architecture allows independent control of two 12-bit data paths on a single chip.
