TI SN74ALS273NSR

These octal positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic 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 (CLK) pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input signal has no effect at the output. The SN54ALS273 is characterized for operation over the full temperature range of -55℃ to 125℃. The SN74ALS273 is characterized for operation from 0℃ to 70℃.
