DM74ALS273WM
数据手册.pdf八路D类边沿触发触发器与Clear Octal D-Type Edge-Triggered Flip-Flop with Clear
General Description
These monolithic, positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic with a direct clear input.
Information at the D inputs meeting the setup requirements is transferred to the Q outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When the clock input is at
either the HIGH or LOW level, the D input signal has no effect at the output.
