概述
Description
NX3DV642GU,115 is a Nexperia two-channel, auto-direction-sensing bidirectional voltage-level translator. It is designed to translate logic signals between two voltage domains (VCCA and VCCB) without a direction pin. Key points:
- Two independent bidirectional channels with auto-direction sensing.
- Interfaces signals between low-voltage and higher-voltage logic (typical I2C/SPI/UART use).
- No dedicated direction control required; handles translation automatically.
- Includes standard ESD protection; intended for small-footprint, low-power digital interconnects.
- Package suffix “GU” indicates a Green (lead-free) package variant; “115” is typically a lot/date code.
For exact electrical specs (VCCA/VCCB ranges, current, propagation delay, OE/enable behavior, etc.), refer to the NX3DV642 datasheet.

Pinout
- Pin count: 8 pins (8-pin package, e.g., SOIC/TSOP)
- Function: NX3DV642GU is a dual 2:1 analog switch (two SPDT channels) with a common select control and tri-state enable. It routes one of two input signals to the output for each channel, used for signal routing/data path selection.

Application
NX3DV642GU,115 is a multi-channel level-shifter/buffer used to interface mixed-voltage I/O and route signals. Common application areas include:
- Level shifting and bidirectional translation between voltage domains (e.g., 1.8/2.5/3.3V to higher levels)
- Bidirectional buffering for I2C, SPI, UART, and general-purpose I/O
- Data-bus switching between MCUs/FPGA/DSP and memories, sensors, ADC/DACs
- Signal conditioning and safe interfacing in mixed-signal systems
- Portable/consumer electronics and automotive/industrial I/O requiring compact, multi-channel interfaces
