• Includes internal D-type flip-flops for storing data from the A or B data buses
• Features select-control inputs to choose between real-time transfer and stored data transmission
• Provides active bus-hold circuitry to maintain valid logic levels on floating inputs

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed transmission of data directly from the data bus or internal storage registers
• Hot-insertion applications utilizing Ioff and power-up 3-state capabilities
• Bus management functions including isolation, storage, and real-time transfer modes
• Unregulated battery operation down to 2.7 V

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DW suffix denotes a tube-packaged SOIC-24 variant. Confirm that the selected part number aligns with the intended operating temperature range and voltage specifications. Ensure all unused control inputs are properly terminated to VCC or GND to guarantee correct device functionality during implementation.

Buffers, Drivers, Receivers, Transceivers Selection Notes
