SN74LVTH273-EP 具有清零功能的增强型产品 3.3V Abt 八路 D 类触发器
This octal D-type flip-flop is designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.
The SN74LVTH273 is a positive-edge-triggered flip-flop with a direct-clear (CLR)\ input. 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 related directly 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.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state
