description

These devices contain two independent positive-edge-triggeredD-type flip-flops. A low level at the preset () or clear () inputs sets or resets the outputsregardless of the levels of the other inputs. When and are inactive (high), data at thedata (D) input meeting the setup-time requirements are transferred tothe outputs on the positive-going edge of the clock (CLK) pulse.Clock triggering occurs at a voltage level and is not directlyrelated to the rise time of CLK. Following the hold-time interval,data at the D input can be changed without affecting the levels atthe outputs.

The SN54ALS74A and SN54AS74A are characterized for operation overthe full military temperature range of -55°C to 125°C. TheSN74ALS74A and SN74AS74A are characterized for operation from0°C to 70°C.
