description/ordering information
The ’HCT652 devices consist of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for
multiplexed transmission of data directly from the data bus or from the internal storage registers. Output-enable
(OEAB and OEBA) inputs are provided to control the transceiver functions. Select-control (SAB and SBA) inputs
are provided to select real-time or stored data transfer. A low input level selects real-time data; a high input level
selects stored data. Figure 1 illustrates the four fundamental bus-management functions that can be performed
with these devices.
