Key Features
- Single-bit 1:1 bus switch with active-low output enable providing near-zero propagation delay for high-speed data bus isolation and signal routing in 2.5 V and 3.3 V systems
- Low on-resistance design minimizing signal attenuation and preserving signal integrity when switching high-frequency digital signals across data bus interfaces
- Compact 5-pin SOT-23 surface-mount package enabling ultra-small board footprint for portable devices, smartphones, and space-constrained PCB designs operating at 2.3 V to 3.6 V
Applications
The 74CBTLV1G125DBVR is commonly used in mobile phones, tablets, and laptops to selectively connect or isolate data bus segments between processors, memory devices, and peripheral interfaces operating at 2.5 V or 3.3 V logic levels. Its near-zero propagation delay and low on-resistance make it suitable for USB, I2C, SPI, and other serial bus switching applications where signal integrity is critical. The device also finds use in battery-powered IoT nodes and wearable electronics where board space is limited and a tiny SOT-23 bus switch is required to manage signal routing between power domains.

Frequently Asked Questions
What is the supply voltage range of the 74CBTLV1G125DBVR?
The 74CBTLV1G125DBVR operates from a supply voltage range of 2.3 V to 3.6 V, making it directly compatible with 2.5 V and 3.3 V logic systems used in modern microprocessors, FPGAs, and peripheral devices.
How does the 74CBTLV1G125DBVR control the bus switch?
The 74CBTLV1G125DBVR uses an active-low output enable pin to control the switch: when the enable pin is asserted LOW, the bus switch connects the input to the output with near-zero propagation delay; when driven HIGH, the switch is open-circuited, isolating the bus segments.
What package does the 74CBTLV1G125DBVR use?
The 74CBTLV1G125DBVR is housed in a 5-pin SOT-23 surface-mount package, one of the smallest standard IC packages available, making it suitable for portable consumer electronics, wearable devices, and any PCB design where board space is at a premium.
What is the switching speed of the 74CBTLV1G125DBVR?
The 74CBTLV1G125DBVR provides near-zero propagation delay characteristic of CBTLV bus switch technology, allowing high-speed digital signals on USB, SPI, I2C, and other serial interfaces to pass through with minimal timing impact compared to traditional logic buffer switches.
What are typical applications for the 74CBTLV1G125DBVR?
Typical applications include data bus isolation in mobile phones and tablets, SPI and I2C bus switching in IoT and wearable devices, signal muxing between microcontrollers and peripheral ICs, and any design requiring a compact, low-voltage single-bit bus switch in a 5-pin SOT-23 package.
