HD74LS273数据手册Renesas中文资料规格书

描述 Description

The HD74LS273, positive-edge-triggered flip-flops utilize LS TTL circuitry to implement D-type flip-flop logic with a direct clear input.
Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse.
When the clock input is at either the high or low level, the D input signal has no effect at the output.
