主要特性和優勢
- 單電源GPIO擴展器，支持1.65 V至5.5 V工作電源電壓范圍
- 通過I²C協議可實現串行到并行（SDA至P0-P16）和并行到串行(P0-P16)轉換
- 在SCL和SDA輸入處，施密特觸發器動作可實現較慢的輸入轉換并提供更好的開關噪聲抗擾度。
- 低功耗：2.5 µA（最大值）
- 工作頻率：400 kHz（FM I²C模式）
- 5 V容差I/O和16個I/O引腳，默認為16路輸入
- 無毛刺上電，所有通道均配置為弱上拉電阻輸入
- 鎖存輸出，具有25 mA最大驅動能力，可直接驅動LED
- 極性反轉寄存器
- 外部復位引腳用于復位狀態機和內部寄存器
- SCL和SDA輸入提供噪聲濾波器
- 封裝選項：TSSOP24和HWQFN24
- 額定溫度范圍為-40 °C至+85 °C和-40 °C至+125 °C
