LSF0204ZMJ12-7

Translators, Level Shifters Overview

The LSF0204ZMJ12-7 is a 4-channel bidirectional multi-voltage level translator designed for open-drain and push-pull applications. It operates with Port A at 0.8V to 4.5V (Vref_A) and Port B at 1.8V to 5.5V (Vref_B). The device supports translation between 0.8V and 5.0V, featuring an active-high enable pin (EN) that ensures high-impedance states during power-up or power-down. It includes ESD protection exceeding 2000V HBM and 1000V CDM, latchup protection exceeding 100mA, and operates from -40°C to +125°C.

Translators, Level Shifters Feature Summary

• Supports bidirectional voltage translation between multiple logic levels including 0.8V, 1.2V, 1.8V, 2.5V, 3.3V, and 5.0V
• Features an active-high enable input that isolates ports in the low state to prevent misoperation during power sequences
• Provides robust ESD protection exceeding JESD 22 standards and latchup protection exceeding 100mA per JESD 17
• Requires external pull-up resistors on both ports to set driving current for push-pull and open-drain configurations

Translators, Level Shifters Applications

• GPIO, MDIO, SDIO, SVID, and UART interfaces
• PMBus, SMBus, I2C, and other communication protocols
• Telecommunications infrastructure systems
• Industrial control equipment
• High-performance computing platforms

Translators, Level Shifters Procurement Notes

Verify the specific package type U-QFN1720-12 matches the design footprint requirements. Confirm the operating temperature range of -40°C to +125°C aligns with system thermal constraints. Ensure external pull-up resistor values are selected to meet the required drive current specifications for the target application load.

Translators, Level Shifters Selection Notes

Select this component when interfacing circuits with varying supply voltages requiring bidirectional data transfer. The device eliminates the need for direction pins through auto-direction sensing capabilities. Verify that Vref_B is maintained at least 1.0V higher than Vref_A to ensure optimal signal integrity across all supported voltage combinations.

Translators, Level Shifters Part Context

This part belongs to the LSF0204 family of universal level translators manufactured by Diodes Incorporated. It is specifically packaged in the U-QFN1720-12 form factor with a 7-inch tape and reel configuration. The suffix ZMJ12 identifies the physical package dimensions and lead configuration unique to this variant within the broader product line.

Translators, Level Shifters Replacement Considerations

LSF0204ZB14-13: Offers identical electrical performance but utilizes a V-QFN3535-14 package. LSF0204T14-13: Provides equivalent functionality in a TSSOP-14 package. Automotive-grade variants such as LSF0204Q exist under separate datasheets.
