The Texas Instruments SN74LV04DR is a hex inverter — six independent NOT gates in a single package, each one performing the basic logic inversion function. It belongs to the LV (Low-Voltage) family, designed to operate at lower supply voltages while maintaining compatibility with TTL logic levels.
Lifecycle and compliance — what the active status means for your BOM
If your assembly line or end-product requires RoHS exemption (e.g., for high-reliability or exempted applications), this part may still be acceptable; for full lead-free compliance, a RoHS-compliant variant like the SN74LV04APWR would be the alternative.
Sourcing the SN74LV04DR
Because the SN74LV04DR is active and RoHS non-compliant, it is not always sitting on every distributor's shelf — many high-volume channels have shifted to lead-free inventory.
