The 74FCT244ATQG8: Output drive is 15mA source and 64mA sink per channel, which gives enough current to drive a standard TTL load or a short PCB trace. The 3-state outputs let multiple buffers share a bus without contention.
For BOM planning, this part is available through independent distribution and can be sourced to order against an RFQ.
The 74FCT244ATQG8 is a different package variant from 74FCT244ATQG. The '8' suffix typically indicates a different packaging or reel option. Verify the package and pin compatibility against your board's footprint before substituting.
No. The 74FCT244ATQG8 requires a 4.75V to 5.25V supply and its input thresholds are designed for 5V logic. It is not suitable for 3.3V logic without level translation.
