SN74ABT273 具有清零功能的八路边沿 D 类触发器
The 'ABT273 are 8-bit positive-edge-triggered D-type flip-flops with a direct clear (
) input. They are particularly suitable for implementing buffer and storage registers, shift registers, and pattern generators.
Information at the data (D) inputs meeting the setup time 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 (CLK) input is at either the high or low level, the D input signal has no effect at the output.
The SN54ABT273 is characterized for operation over the full military temperature range of -55°C to 125°C
