SN54ALS74A 的說明
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 are transferred to
the outputs on the positive-going edge of the clock (CLK) pulse.
Clock triggering occurs at a voltage level and is not directly
related to the rise time of CLK. Following the hold-time interval,
data at the D input can be changed without affecting the levels at
the outputs.
The SN54ALS74A and SN54AS74A are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS74A and SN74AS74A are characterized for operation from 0°C to 70°C.
