The UT54ACS273 and the UT54ACTS273 are positive-edgetriggered D-type flip-flops 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. The devices are characterized over full military temperature range of -55 C to +125 C.
