The 74FCT2244CTQG: Each output can source 15mA and sink 12mA. The 3-state disable puts the outputs into a high-impedance state.
It handles the thermal swing inside an outdoor telecom cabinet, a factory-floor PLC enclosure, or an engine-bay controller without derating. Not qualified to AEC-Q100, so not the first pick for automotive safety-critical paths — but fine for non-automotive industrial gear where the environment stays within that envelope.
It is a dual 4-bit non-inverting buffer with 3-state outputs. Each element buffers four bits independently, and the outputs can be tri-stated to float the bus when the buffer is not selected.
No, this part is designed for a 4.75V to 5.25V supply. Its input thresholds are 5V CMOS/TTL levels. Driving it from a 3.3V output without level translation will not reliably reach the logic-high threshold. Use a 5V-tolerant buffer or a level shifter if interfacing to 3.3V logic.
