The 15mA high-level and 64mA low-level output current ratings define the fan-out on a 5V bus. At 64mA sink, you can drive up to ten standard TTL loads per channel without exceeding the package thermal limit.
That makes it safe for new designs and production BOMs without an obsolescence contingency. The 74FCT series is a mature logic family with broad distribution coverage; sourcing through independent channels is straightforward.
No. The supply range is 4.75V to 5.25V, and the input thresholds are TTL-compatible for 5V operation. Driving it from a 3.3V output will not reliably cross the high-level input threshold. Use a 5V-tolerant level translator or a dedicated 3.3V bus transceiver instead.
It comes in a 20-SSOP package (0.209", 5.30mm width) for surface-mount assembly. The supplier device package is also listed as 20-SSOP.
