PRODUCTION DATA information is current as of publication date. Productsconform to specifications per the terms of Texas Instruments standard warranty.Production processing does not necessarily include testing of all parameters.
These devices contain two independent D-type positive-edge-triggered flip-flops.A low level at the preset or clear inputs sets or resets the outputs regardlessof the levels of the other inputs. When preset and clear are inactive (high),data at the D input meeting the setup time requirements are transferred tothe outputs on the positive-going edge of the clock pulse. Clock triggeringoccurs at a voltage level and is not directly related to the rise time ofthe clock pulse. Following the hold time interval, data at the D input maybe changed without affecting the levels at the outputs.
The SN54' family is characterized for operation over the full militarytemperature range of -55°C to 125°C. The SN74' family is characterizedfor operation from 0°C to 70°C.
