• Bidirectional data bus interfacing
• Memory-to-I/O data transfers
• Bus-oriented memory and command decoding

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'N3' against current Texas Instruments documentation. Standard catalog listings typically utilize 'N' or 'N.A' for PDIP packages. Confirm that the requested variant matches active production status and lead finish specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-drive capacity on bidirectional buses. The open-collector architecture allows connection to external pull-up resistors, enabling operation with varying voltage levels at the receiving end compared to the driver supply.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LS64x series of octal bus transceivers. While the datasheet covers variants like SN74LS641-1N, verify if the '3' suffix denotes a specific manufacturing lot code or regional variation rather than a distinct functional model.
