General Description

/ordering information NC − No internal connection 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 ’BCT646 devices.
