The control function implementation minimizes external timing requirements. The device allows data transmission from the A bus to the B bus or adtasheet the B bus to the A bus depending upon the logic level at the direction control DIR input. A critical component is any component of a life support datqsheet 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. The parallel interface can be connected to a tri-level bus through a 74LS or equivalentcrystal frequency is No abstract text available Text: Previous 1 2 Both serial and parallel interfaces are74lss245 for data processing.
