Digilent Pmod LVLSHFT是一個內建 Texas Instruments SN47LVC1T45 接收器的數位邏輯電平轉換模組。該模組適用於需要在3.3V CMOS標準的邏輯訊號,但具有備用邏輯電平輸出的使用者。
- 數位邏輯電平轉換器
- 能在兩個使用者提供的電壓電平之間轉換邏輯訊號
- 2×7 pin JTAG 接頭
- 用於控制邏輯層轉換的8個迷你開關
- 支援 1.8~5.5V 電壓
- 適用於各種設計的小型PCB (4.6cm*2.0cm)
- 具有 GPIO 介面的 12 pin Pmod 連接器
- 排針上的插針間距為100 mil。 PCB在與排針上的針平行的側面上長1.75英寸,在與排針垂直的側面上長0.8英寸。
