It draws its supply from a 4.75V to 5.25V rail — standard 5V logic territory, so it sits comfortably alongside legacy TTL or 5V CMOS parts in a mixed-voltage board. Output drive capability is 15 mA sourcing and 64 mA sinking — the asymmetric ratio is typical of bipolar-derived logic and means the low-level output can fan out to a heavier load than the high-level side. For a backplane or memory-address buffer driving multiple CMOS inputs, the 64 mA sink handles the capacitive load without external pull-ups. ## Through-hole DIP package and board integration Housed in a 20-pin plastic DIP with 0.300-inch row spacing (7.62 mm), the CD74FCT541E is a through-hole part meant for prototyping, rework-friendly designs, or legacy board spins that cannot migrate to surface-mount. The 20-PDIP supplier package code matches the standard DIP-20 footprint — no surprises on the layout side. If your system sees -20°C or +85°C, this part is outside its guaranteed operating envelope. ## Active lifecycle and compliance status That means it remains a valid BOM line for new production runs without a lifecycle risk flag. No pin-compatible second-source or successor is recorded in the manufacturer's cross-reference data — the 74FCT family is the only official lineage.","metaTitle":"CD74FCT541E 74FCT Buffer, Non-Inverting, 3-State, 20-DIP","metaDescription":"CD74FCT541E active 74FCT buffer with 15mA/64mA output drive, 4.75V-5.25V supply, through-hole 20-DIP package.
