The output drive capability — 32 mA source, 64 mA sink — is sized for driving moderate capacitive loads on parallel data buses or fanning out to multiple CMOS inputs without external line drivers. ## Where it fits in the 74FCT family The 74FCT series is a high-speed, low-power BiCMOS logic family that is functionally compatible with the 74F (Fast) series but with reduced quiescent current. The CY74FCT541ATQCT is a direct drop-in for any 74FCT541 or 74F541 footprint, though the 74FCT variant typically draws lower supply current at the same propagation delay. If you need a transceiver (bidirectional) instead of a buffer, the SN74ABT2245DW or SN74LVTH16245ADGVR are 8-bit transceivers with similar supply voltage ranges, but note the different pinouts and direction-control pins.","metaTitle":"CY74FCT541ATQCT 74FCT Buffer, Non-Inverting, 3-State","metaDescription":"CY74FCT541ATQCT 74FCT buffer with 3-state output, 4.75V-5.25V supply, 32/64mA drive, -40°C to 85°C, 20-SSOP.
