Description for the SN74F74
These devices contain two independent positive-edge-triggered
D-type flip-flops. A low level at the preset (
) or clear (
) inputs sets or resets the outputs
regardless of the levels of the other inputs. When and are inactive (high), data at the
data (D) input meeting the setup time requirements 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°C to 125°C. The SN74F74 is characterized for operation from 0°C to 70°C.
The output levels are not guaranteed to meet the minimum
levels for VOH. Furthermore, this configuration is
nonstable; that is, it will not persist when or returns to its inactive (high) level.
