Description:
The NTE7474 contains two independent D−type positive−edge−triggered flip−flops in a 14−Lead DIP
type package characterized for operating from 0° to +70°C. A low level at the preset or clear inputs
sets or resets the outputs regardless of the levels of the other inputs. When preset and clear are inac-
tive (high), data at the D input meeting the setup time requirements are 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.
