Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer origin, as NXP and Motorola also produce parts under this designation. Confirm the package type matches the required installation method, as variants exist in SOIC and other surface-mount formats. Ensure the revision level aligns with current RoHS compliance standards before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing TTL-compatible digital circuits requiring isolated bus buffering. The LS series offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the 14-pin DIP package for prototyping or through-hole manufacturing processes where surface-mount technology is not feasible.
