description/ordering information

These devices consist of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed

transmission of data directly from the input bus or from the internal registers. Data on the A or B bus is clocked

into the registers on the low-to-high transition of the appropriate clock (CLKAB or CLKBA) input. Figure 1

illustrates the four fundamental bus-management functions that can be performed with the ’ABT646A devices.
