TXB0104 電壓位準 I/O轉換板 4bit SparkFun原廠

NT$119 NT$114 未稅

Texas Instruments TXB0104 模組的擴展板。TXB0104是一款具有自動方向感應功能的4位雙向電壓電平轉換器。這個4位非反相轉換器使用兩個獨立的可配置電源軌。A端口旨在跟踪VCCA。VCCA接受1.2V至3.6V的任何電源電壓。B端口用於跟踪VCCB。VCCB接受1.65V至5.5V的任何電源電壓。這允許在1.2V,1.5V,1.8V,2.5V,3.3V和5V電壓節點之間進行通用的低壓雙向轉換。VCCA不應超過VCCB。我們已經打破了這個模塊上的每個引腳,您可以輕鬆訪問A和B端口。

SparkFun電壓電平轉換器突破 -  TXB0104


  • A端口為1.2V至3.6V,B端口為1.65V至5.5V(VCCA≤VCCB)
  • VCC隔離功能 – 如果VCC輸入處於GND,所有輸出都處於高阻狀態
  • OE輸入電路參考VCC
  • 低功耗,5μA最大ICC





This is a breakout board for the Texas Instruments TXB0104 module. The TXB0104 is a 4-bit bidirectional voltage-level translator with automatic direction sensing.

This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB. We have broken out each pin on this module for you to easily access both the A and B ports.

  • 1.2V to 3.6V on A Port and 1.65V to 5.5V on B Port (VCCA ≤ VCCB)
  • VCC Isolation Feature – If Either VCC Input Is at GND, All Outputs Are in the High-Impedance State
  • OE Input Circuit Referenced to VCC
  • Low Power Consumption, 5-μA Max ICC
