Key Features
- 4-bit bidirectional voltage level translation supporting both open-drain and push-pull signaling modes
- Wide voltage range: operates from 1.65V to 5.5V on both A and B ports for flexible multi-rail designs
- Fast propagation delay of 45ns max enabling high-speed I2C, SPI, and general logic level shifting
- Compact QFN-12 (WSON) package ideal for space-constrained PCB designs
- Single-supply or dual-supply operation with automatic direction sensing — no direction control pin needed
Applications
The LSF0204DRUTR is widely used in mobile phones, tablets, and IoT devices where mixed-voltage buses require seamless level shifting between 1.8V microcontrollers and 3.3V or 5V peripherals. It is also deployed in industrial automation and robotics systems for translating signals between I2C, SPI, or GPIO lines across different logic domains. Battery-powered wearables and embedded computing modules benefit from its low quiescent current and open-drain compatibility for multi-master bus architectures.

Frequently Asked Questions
What voltage levels does the LSF0204DRUTR support?
The LSF0204DRUTR supports voltage translation between 1.65V and 5.5V on both the A and B ports. This makes it compatible with common logic levels including 1.8V, 2.5V, 3.3V, and 5V, allowing flexible interfacing between modern low-voltage microcontrollers and legacy 5V peripherals.
Can the LSF0204DRUTR be used for I2C level shifting?
Yes, the LSF0204DRUTR is well-suited for I2C level shifting because it supports open-drain output mode, which is required by the I2C protocol. Its bidirectional operation with automatic direction sensing means no OE or DIR control signal is needed, simplifying PCB design for multi-master I2C buses.
What is the maximum propagation delay of the LSF0204DRUTR?
The LSF0204DRUTR has a maximum propagation delay of 45ns, which is sufficient for standard I2C (up to 1MHz Fast-mode Plus) and many SPI applications. This low delay ensures signal integrity when translating logic levels between high-speed digital buses in embedded systems.
What package does the LSF0204DRUTR come in and what are the dimensions?
The LSF0204DRUTR is available in a 12-pin WSON (QFN) package with a small footprint, making it ideal for space-constrained designs. The 'R' suffix in the part number indicates tape-and-reel packaging, and the 'TR' suffix denotes a standard reel quantity, which is convenient for automated SMT assembly.
