Inverter Gates Procurement Notes

Verify the specific suffix DTG4 against official Texas Instruments documentation to confirm the SOIC-14 package variant and RoHS compliance status. Ensure the ordering part number matches the exact manufacturing revision required for your design. Cross-reference the datasheet for any recent pinout or electrical specification updates before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when interfacing between 5V CMOS logic families and systems requiring noise immunity. The HCT series ensures compatibility with TTL input levels while maintaining CMOS power efficiency. Consider the 14-pin SOIC footprint for PCB layout constraints and verify that the 4.5V to 5.5V operating range aligns with the target system power supply.

Inverter Gates Part Context
