Part Number : SNJ54HCT652JT
Function : OCTAL BUS TRANSCEIVERS AND REGISTERS WITH 3-STATE OUTPUTS
Manufacturers : Texas Instruments
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.
