Pull-Up Resistor Equations Where: N1 (IOH) = total maximum output HIGH current for all outputs tied to pull-up resistor N2 (IIH) = total maximum input HIGH current for all inputs tied to pull-up resistor N3 (IIL) = total maximum input LOW current for all inputs tied to pull-up resistor
This DM74ALS38A device contains four independent gates, each of which performs the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation.
The DM74ALS38A has six features.The first one is switching specifications at 50 pF.The second one is switching specifications guaranteed over full temperature and VCC range.The third one is advanced oxide-isolated, ion-implanted Schottky TTL process.The fourth one is functionally and pin for pin compatible with LS TTL counterpart.The fifth one is improved AC performance over LS38.The sixth one is improved line receiving characteristics.The DM74ALS38A has some absolute maximum ratings.When parameter is supply voltage,the rating is 7V.When parameter is input voltage,the rating is 7V.When parameter is high level output voltage,the rating is 7V.When parameter is operating free air temperature range,the rating is 0 to +70.When parameter is storage temperature range,the rating is -65 to +150.When parameter is typical JA N Package,the rating is 83.0/W.When parameter is typical JA M Package,the rating is 114.0/W..
Life support devices or systems are devices or systems which, (a) are intended for surgical implant into the body, or (b) support or sustain life, and (c) whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.A critical component in any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support DM74ALS38A device or system, or to affect its safety or effectiveness.
