The CY74FCT2244ATQCT is a dual non-inverting buffer from Texas Instruments, part of the 74FCT logic family. It operates at 4.75V to 5.25V, with 15mA sink and 12mA source output current. Featuring 3-State outputs and a 20-SSOP package, it is designed for high-speed 5V bus driving and TTL interfacing in industrial and telecom applications.
- High Output Drive (15mA/12mA): Ensures reliable signal transmission over long, capacitive buses.
- TTL-Compatible Inputs: Directly interfaces with legacy TTL logic without additional circuitry.
- 3-State Outputs: Facilitates bus sharing and isolation, improving system flexibility.
- Compact SSOP Package: Reduces PCB footprint, ideal for space-constrained designs.
High-Speed 5V Bus Driving
The CY74FCT2244ATQCT drives high-capacitance buses in 5V systems. With 15mA sink and 12mA source capability, it maintains fast edge rates, essential for high-speed data transfer in legacy TTL backplanes.
Memory Address Buffering
In DRAM or SRAM controllers, this buffer isolates address lines from the memory array. The 3-State outputs allow the address bus to be tri-stated during refresh cycles, preventing data corruption.
TTL to CMOS Level Conversion
It interfaces TTL logic (4.75V-5.25V) to CMOS inputs. The FCT family's TTL-compatible thresholds ensure reliable switching, while the non-inverting function preserves signal polarity.
Industrial Control I/O Expansion
In PLCs, it buffers output signals to multiple actuators. The high drive current ensures reliable switching of relays and solenoids, while 3-State outputs allow for safe system shutdown.
Telecom Line Card Interface
For telecom line cards, this buffer drives signals across the backplane. The 5V operation matches standard telecom logic, and the SSOP package saves space on dense line cards.
