The SN74BCT956 consists of bus transceiver circuits, D-type latches, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal latches. Data on the A or B bus is stored in the latches when the appropriate latch-enable (LEAB or LEBA) input is low. Figure 1 illustrates the four fundamental bus-management functions that can be performed with the SN74BCT956. Output-enable (OE) and direction-control (DIR) inputs are provided to control the transceiver functions. In the transceiver mode (OE low), data present at the high-impedance port may be stored in either latch or in both. The select-control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode) data. When the appropriate latch-enable input is high, the latch is transparent, and real-time data is output regardless of the level at the select control. |
