The CD74FCT2244ATM from Harris Corporation is a high-speed CMOS buffer designed for 5V bus systems. It features a single non-inverting channel with 3-State outputs, allowing for safe bus sharing. With a sink capability of 64mA and source of 15mA, it provides strong drive for capacitive loads. Operating from 4.75V to 5.25V, it is compatible with standard TTL logic. The 20-SOIC package is ideal for surface-mount designs in industrial and computing applications.
- High Sink Current (64mA): Provides excellent drive for LEDs, relays, and high-capacitance bus lines.
- 3-State Outputs: Enables bus multiplexing, preventing data contention in multi-device systems.
- Wide 5V Supply Range (4.75V to 5.25V): Ensures compatibility with standard 5V logic rails.
- Industrial Temperature Range (-40°C to 85°C): Suitable for harsh operating environments.
