What are the key features of 74CB3Q3257DBQRG4?
- Quad 2:1 bidirectional mux/demux routes 4-bit buses with near-zero propagation delay for transparent switching
- 1.65 V to 3.6 V supply range makes it compatible with 1.8 V and 3.3 V mixed-voltage bus interfaces
- 50 pF load drive capability and active bus-hold inputs prevent floating lines in bidirectional signal paths
What is 74CB3Q3257DBQRG4 used for?
The 74CB3Q3257DBQRG4 is used in memory interface routing, peripheral bus switching, and data path multiplexing on boards where a 4-bit bus must be shared between two sources. Its near-zero propagation delay and bidirectional operation make it suitable for DDR memory address switching, I2C/SPI bus sharing, and FPGA I/O expansion in 1.8 V or 3.3 V systems. The compact 16-pin SSOP footprint fits easily on space-constrained PCBs in networking, storage, and embedded computing designs.
