Inverter Gates Procurement Notes

Verify the specific suffix 'G4' indicates the green/RoHS-compliant variant when ordering. Confirm that the SOIC package matches the required footprint dimensions of 8.70 mm by 3.90 mm. Ensure the design accounts for the AEC-Q100 Grade 1 qualification requirements if deployed in safety-critical automotive systems. Cross-reference the datasheet revision D specifications against existing inventory to ensure parameter consistency.

Inverter Gates Selection Notes

Select this component when a quadruple XOR function is required in space-constrained automotive designs. The HC series offers significant power reduction compared to LSTTL equivalents while maintaining compatibility with standard CMOS logic levels. Consider the 14-pin SOIC package for surface-mount assembly where thermal resistance and board space are limiting factors. Verify input signal edge rates comply with recommended transition times to prevent excessive current consumption.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating; they should be terminated to either VCC or ground using pull-up or pull-down resistors to prevent undefined operational states.

What is the maximum recommended capacitive load?

The device can drive loads up to 50 pF while meeting all specifications. Loads exceeding 70 pF are not recommended unless a series resistor is added to limit output current.
