SN54F74 contains two independent positiveege-triggered D-type flip-flops. A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs regardless of the levels of the other inputs. When PRE and CLR are inactive (high),data at the data (D) input meeting the setup time requirements SN54F74 is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse.Following the hold-time interval, data at the D input may be changed without affecting the levels at the outputs.
The SN54F74 is characterized for operation over the full military temperature range of -55 to 125. The SN74F74 is characterized for operation from 0 to 70.
