Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'DW' corresponds to the SOIC-20 surface-mount package. Check for end-of-life status or obsolescence notices prior to procurement to ensure long-term supply stability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring bidirectional octal transfer with integrated latching. Ensure the logic family compatibility matches existing TTL inputs. Verify that the 20-SOIC footprint aligns with the PCB layout constraints and thermal requirements of the target application environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LS623 family of octal bus transceivers. It is distinct from the SN74LS374 latch by providing bidirectional transfer rather than unidirectional storage. The device integrates local latching functionality directly into the transceiver architecture.

Buffers, Drivers, Receivers, Transceivers FAQ

Does the SN74LS623DW support bidirectional data flow?

Yes, it is designed as a bidirectional bus transceiver allowing data transfer in both directions.

What is the purpose of the local bus-latch capability?

It allows the device to capture and hold data locally on the bus, improving system timing and control flexibility.
