DM74AS21

This DM74AS21 device contains two independent 4-input gates,each of which performs the logic AND function.

The DM74AS21 has five 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 Schottky,low power Schottky, and advanced low power Schottky TTL counterpart.The fifth one is improved AC performance over Schottky, low power Schottky and advanced low power Schottky counterparts.The DM74AS21 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 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 84.0/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 device or system, or to affect its safety or effectiveness.
