OCTAL BUS TRANSCEIVERS AND REGISTERS WITH 3-STATE OUTPUTS

The HCT652 consist of bus-transceiver SN54HCT652 SN74HCT652 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 the HCT652. Data on the A or B data bus, or both, CAN be stored in the internal D-type Flip-Flops by low-to-high transitions at the appropriate Clock (CLKAB or CLKBA) terminals regardless of the select- or output-control terminals. When SAB and SBA are in the real-time transfer mode, it is possible to store data without using the internal D-type Flip-Flops by simultaneously enabling OEAB and OEBA. In this configuration, each output reinforces its input. When all other data sources to the two sets of bus lines are at high impedance, each set of bus lines remains at its last state. The SN54HCT652 is characterized for operation over the full military temperature range of 55C to 125C. The SN74HCT652 is characterized for operation from 40C to 85C. By Texas Instruments
