MC74AC823N中文资料摩托罗拉数据手册PDF规格书

The MC74AC/ACT823 consists of nine D-type edge-triggered flip-flops. This device has 3-state outputs for bus systems, organized in a broadside pinning. In addition to the clock and output enabled pins, the buffered clock (CP) and buffered Output Enable (OE) are common to all flip-flips. The flip-flops will store the state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH CP transition. With OE LOW, the contents of the flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high impedance state.
