74HC299;74HCT299是高速硅栅CMOS器件,与低功耗肖特基TTL (LSTTL)针脚兼容。该类器件的规格符合JEDEC标准no. 7A。
74F299包含八个边沿触发D型触发器和执行同步右移、左移、并行负载和保持操作所必需的级间逻辑。操作由模式选择输入S0和S1确定。
针脚I/O0至I/O7是触发器3态缓冲器输出,这允许它们在并行负载模式中用作数据输入。串行输出Q0和Q7用于在较长字的串行位移中实现扩展。
MR异步主复位输入上的低电平信号覆盖Sn和时钟CP输入并复位触发器。所有其他状态变化由时钟脉冲的上升沿启动。只要遵照建议的设置和保持时间,时钟处于任意状态时输入都可能发生变化。
3态输出使能输入OE1或OE2上的高电平信号会禁用3态缓冲器且I/On输会被置于高阻抗关断状态。在这种情况下,准备并行负载操作时移位、保持、负载和复位操作仍会发生。3态缓冲器还可由S0和S1上的高电平信号禁用。
