Frequently Asked Questions
How many bits can the 74CBTK16245DLRG4 switch simultaneously, and how is each channel enabled?
The 74CBTK16245DLRG4 switches 16 bits in parallel controlled by an active-low enable pin; asserting the enable low connects all 16 FET switches simultaneously, making it ideal for word-wide bus isolation and data path multiplexing.
What load capacitance is the 74CBTK16245DLRG4 characterized at, and why does that matter for signal integrity?
The device is characterized at 50 pF load capacitance per channel, which reflects typical PCB trace loading; its low FET on-resistance minimizes RC delay and preserves signal rise and fall times even at high bus clock frequencies.
In which PCB package does the 74CBTK16245DLRG4 come, and how does that affect board layout density?
The part ships in a 48-pin SSOP package with fine-pitch leads, allowing a 16-bit bus switch to fit in a much smaller PCB footprint than comparable DIP or SOIC alternatives, benefiting compact backplane and daughtercard designs.
When would the 74CBTK16245DLRG4 be chosen over a standard 74245 bus transceiver in a 3.3V system?
Unlike a 74245 transceiver which drives signals with active pull logic, the 74CBTK16245DLRG4 uses FET switches that create a near-transparent path with minimal propagation delay and no drive contention risk, making it preferable for 3.3V hot-swap or live-insertion bus architectures.
