description

These octal positive-edge-triggered flip-flops utilize TTLcircuitry to implement D-type flip-flop logic with a direct-clear() input.

Information at the data (D) inputs meeting the setup-timerequirements is transferred to the Q outputs on the positive-goingedge of the clock (CLK) pulse. Clock triggering occurs at aparticular voltage level and is not directly related to thetransition time of the positive-going pulse. When CLK is at eitherthe high or low level, the D input signal has no effect at theoutput.

The SN54ALS273 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74ALS273 is characterized for operation from 0°C to 70°C.
