What this 74FCT3244SOG does on your board
The Renesas 74FCT3244SOG is a dual 4-bit buffer with non-inverting outputs and 3-state control. Supply range is 2.7V to 3.6V. Output drive is asymmetric: 8 mA source, 24 mA sink. That sink capability is useful for driving relay coils or indicator LEDs where the load returns to the supply rail. The 3-state outputs let you share a bus without contention – pull the output-enable pins high and the outputs go high-impedance. Industrial temperature range (-40°C to 85°C) covers factory-floor cabinets, outdoor telecom pedestals, and engine-bay electronics that see thermal cycling. The 20-SOIC wide-body package (7.50 mm width) is a common footprint; verify your PCB land pattern matches the 0.295" body width before layout.
Lifecycle and sourcing – no end-of-life concern
The 74FCT3244SOG carries an Active lifecycle status. For a BOM line that needs a reliable 3.3V buffer, this part does not carry obsolescence risk.
