Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific LVTH series designation against the datasheet to ensure compatibility with 3.3V logic levels. Confirm that the SOIC-20 package dimensions match the target PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the system's thermal constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require octal buffering with three-state control at 3.3V logic levels. The LVTH series offers a balance between speed and power consumption compared to standard TTL or CMOS alternatives. Consider the 2.6 ns propagation delay for timing-critical paths. Verify input voltage thresholds align with the driving source logic family.
