• Invert a digital signal

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'TG4' against the manufacturer's current documentation to confirm lead-free status and RoHS compliance details. Ensure the package type matches the required SOIC-14 footprint and that the thermal resistance values align with the intended PCB layout design constraints.

Inverter Gates Selection Notes

Select this component when designing circuits requiring noise immunity for slow or noisy input signals. It is suitable for applications needing to drive multiple LSTTL loads while maintaining low power consumption. Verify that the output capacitive load does not exceed recommended limits to prevent ringing and ensure signal integrity.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must be terminated at VCC or GND to prevent undefined operational states caused by floating voltages.

What is the maximum recommended capacitive load?

The datasheet recommends ensuring the capacitive load at the output is less than or equal to 70 pF for optimal performance.
