These devices can be used as two 8-bit transceivers or one 16-bit transceiver.
Output-enable (OEAB and OEBA) inputs are provided to control the transceiver functions.
Select-control (SAB and SBA) inputs are provided to select whether real-time or stored data is transferred.
The circuitry used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data.
A low input selects real-time data, and a high input selects stored data.
Figure 1 illustrates the four fundamental bus-management functions that can be performed with the ’ABT16652.
