Procurement Notes

Verify the specific package type (TSSOP) and tape-and-reel configuration when ordering. Confirm that the component meets the required operating temperature range of -55°C to 125°C for your application environment. Ensure compatibility with the 4.5V to 5.5V supply voltage specifications. Check for any RoHS compliance requirements if applicable to your manufacturing standards.

Selection Notes

Select this component when a hex inverter with high-speed performance and TTL-compatible input/output levels is required. Consider the TSSOP-14 package for surface-mount assembly needs. Evaluate the 5.0ns typical propagation delay against system timing constraints. Verify that the 24mA output drive current is sufficient for the connected loads and transmission line requirements.
