LSF0202DCH

Translators, Level Shifters Overview

The LSF0202DCH is a 2-bit bidirectional multi-voltage level translator manufactured by Nexperia, housed in an 8-lead VSSOP package (SOT765-1). It supports open-drain and push-pull applications with independent voltage translation on each channel. The device operates within a temperature range of -40 °C to +125 °C and features low standby current. Input/output pins are 5 V tolerant, ensuring compatibility with TTL levels. The component includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM), along with latch-up performance exceeding 100 mA per JESD78 class II.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation without requiring a direction pin
• Supports hot insertion for flexible system integration
• Low on-resistance minimizes signal distortion across channels
• High-impedance I/O state available when the enable input is low

Translators, Level Shifters Applications

• GPIO, MDIO, PMBus, SMBus, SDIO, UART, and I2C interfaces in telecom infrastructure
• Industrial control systems
• Personal computing devices

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix DCH corresponds to the VSSOP8 (SOT765-1) package variant as defined in the manufacturer's ordering table. Confirm that the required voltage translation ranges align with the supported combinations listed in the datasheet. Ensure design compliance with the specified operating temperature limits and absolute maximum ratings to prevent device damage.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between different logic voltage domains is required without complex control logic. The LSF0202 differs from the LSF0102 only in pin assignment; verify pinout compatibility with the target PCB layout. The flow-through pinout facilitates easy routing. Ensure the application does not exceed the recommended operating conditions for input currents or power dissipation.

Translators, Level Shifters Part Context

This part belongs to the LSF0102/LSF0202 family of 2-channel voltage translators. While functionally identical regarding electrical performance, the LSF0202 utilizes a distinct pin configuration compared to the LSF0102. Both variants share the same core capabilities for translating signals between various voltage levels such as 1.2V, 1.8V, 2.5V, 3.3V, and 5.0V.

Translators, Level Shifters Replacement Considerations

The LSF0102DC serves as a functional substitute with identical electrical specifications but requires verification of pinout differences against the current schematic design.
