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.
Features:
- 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

這是德州儀器TXB0104模塊接口板。該TXB0104是一款4位雙向電壓電平轉換器與自動方向感應。
這4位同相翻譯使用兩個獨立的可配置電源軌。 A端口設計用於跟踪VCCA。 VCCA接受來自1.2V至3.6V的電源電壓。端口B用於追踪VCCB。 VCCB接受來自1.65V至5.5V的電源電壓。這允許任何的1.2-V，1.5-V，1.8-V，2.5-V，3.3 V，和5 V電壓節點之間普遍低壓雙向轉換。 VCCA不應超過VCCB。我們已經打破了每個引腳該模塊為您輕鬆訪問兩個A和B的端口上。
特徵：
- 1.2V至3.6V的端口和1.65V至5.5V的第B端口（VCCA VCCB≤）
- VCC隔離特性 - 如果任一VCC輸入為GND，所有輸出都在高阻抗狀態
- OE輸入電路參照VCC
- 低功耗，5μA最大ICC
