This device is a 16-bit transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an Output Enable (OE) input for easy cascading and a Direction (DIR) input for direction control. Data on the A or B bus is clocked into the registers on the Low to High transition of the appropriate clock (CPAB or CPBA). The select-control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode data). QUICK R...
