Non-inverting, tri-state outputs allow multiple drivers on a shared bus without contention. This is a straight-through bus driver, not a latch or register. ## Active, but watch the RoHS flag That rules it out for any new design that must meet RoHS or lead-free assembly requirements. For legacy repairs or exempt military/industrial builds, the lead-bearing finish is often preferred for reliability in high-temperature or high-vibration environments. ## Not a drop-in for the 74FCT573 latch A common cross-shop candidate is the 74FCT573APC, an 8-bit D-type transparent latch. The CY74FCT841CTQC is a bus driver, not a latch — it lacks the latch-enable control and does not hold data when the clock is removed. If your design needs registered or latched outputs, the 74FCT573APC (through-hole, 4.75 V supply, 8.5 ns propagation delay) serves that function. The CY74FCT841CTQC is for unbuffered bus expansion where you need high drive strength and tri-state control only. ## Sourcing and verification Because the CY74FCT841CTQC is RoHS non-compliant, buyers should confirm the date-code and marking match Cypress's factory format — especially on surplus or broker stock. The laser etch on the package should be sharp, consistent, and free of re-marking. Request an RFQ for your BOM line.","metaTitle":"CY74FCT841CTQC Bus Driver, FCT Series, Active","metaDescription":"CY74FCT841CTQC bus driver from Cypress, FCT series, active lifecycle.
