What are the key features of 74CBTLV1G125DCKR?
- Ultra-low 5-ohm on-resistance for minimal signal degradation across the bus
- Wide supply voltage range from 1.65 V to 5.5 V for mixed-voltage designs
- Compact 5-pin SC-70 package ideal for space-constrained PCB layouts
What is 74CBTLV1G125DCKR used for?
The 74CBTLV1G125DCKR is widely used in portable consumer electronics and handheld devices where level translation between 1.8 V and 3.3 V logic domains is required. It serves as a bus isolator in microcontroller systems, enabling controlled data routing on I2C or SPI buses. Its tiny footprint and low on-resistance also make it suitable for battery-powered IoT sensor nodes.

Frequently Asked Questions
What on-resistance does the 74CBTLV1G125DCKR offer and why does it matter for high-speed buses?
The 74CBTLV1G125DCKR features a typical on-resistance of 5 ohms, which minimises the resistive voltage drop across the switch during data transfer. This low resistance helps preserve signal integrity on buses operating at frequencies up to 200 MHz, making it well suited for high-speed SPI or I2C links in portable designs.
Which supply voltage rails does the 74CBTLV1G125DCKR support in mixed-voltage systems?
The device operates from a supply voltage of 1.65 V to 5.5 V, covering common logic rails including 1.8 V, 2.5 V, 3.3 V, and 5 V. This broad range makes it suitable for mixed-voltage board designs where signals must pass between different logic-level domains without external level shifters.
How does the SC-70 5-pin package of the 74CBTLV1G125DCKR compare to SOT-23 in PCB footprint?
The SC-70 package measures approximately 2.0 mm x 1.25 mm, roughly 30% smaller than a standard SOT-23 footprint. This size advantage allows designers to place the 74CBTLV1G125DCKR in tightly constrained areas of wearable or handheld PCBs while still using standard reflow soldering with 0.65 mm pitch pads.
