Frequently Asked Questions
What on-resistance does the 74CBTK16245DGVRE4 offer, and why does it matter for signal integrity?
The 74CBTK16245DGVRE4 features a typical on-resistance of approximately 5 Ω, which minimizes voltage drop and signal distortion across the 16 switch channels. At 50 pF load capacitance, this low resistance supports data rates up to 800 Mbps, making it suitable for high-speed bus interconnects in servers and networking equipment.
Which supply voltage ranges are compatible with the 74CBTK16245DGVRE4 for a mixed-voltage board design?
The 74CBTK16245DGVRE4 operates from a 2.3 V to 3.6 V supply, covering both 2.5 V and 3.3 V logic systems. This range allows seamless integration on boards that mix legacy 3.3 V peripherals with newer 2.5 V digital logic, reducing the need for separate level-translation circuits and simplifying board layout.
How many switch channels does the 74CBTK16245DGVRE4 provide, and what is the package configuration?
The device provides 16 bidirectional FET switch channels controlled by a single active-low enable pin. It is housed in a 48-pin TSSOP package, which offers a compact PCB footprint of approximately 6.1 mm × 12.5 mm, suitable for space-constrained applications such as memory modules and high-density backplanes.
When should a designer choose the 74CBTK16245DGVRE4 over a standard logic buffer for bus connection?
A FET bus switch like the 74CBTK16245DGVRE4 introduces only about 5 Ω of on-resistance and no propagation delay through active logic stages, whereas a standard buffer adds 3–7 ns propagation delay and requires separate power-up sequencing. For 800 Mbps data paths where latency and signal fidelity are critical, the FET switch approach is preferable.
