CD4094是帶輸出鎖存和三態控制的串入/並出高速轉換器，具有使用簡單、功耗低、驅動能力強和控制靈活等優點。
CD4094的引腳圖及引腳描述
其中(1)腳為鎖存端，
(2)腳為串列數據輸入端，
(3)腳為串列時鐘端。(1)腳為高電平時，8位并行輸出口Q1～Q8在時鐘的上升沿隨串列輸入而變化；(1)腳為低電平時，輸出鎖定。利用鎖存端可方便地進行片選和級聯輸出控制。
(15)腳為并行輸出狀態控制端，(15)腳為低電平時，并行輸出端處在高阻狀態，在用CD4094作顯示輸出時，可使顯示數碼閃爍。(
9)腳QS、(10)腳Q′S是串列數據輸出端，用於級聯。QS端在第9個串列時鐘的上升沿開始輸出，Q′S端在第9個串列時鐘的下降沿開始輸出。
當CD4094電源為5V時，輸出電流大於3．2MA，灌電流為1 MA。串列時鐘頻率可達2．5MHZ。
