The CY74FCT2240TS0C is a high-speed inverting buffer from Texas Instruments, part of the 74FCT logic family. It features two channels with 3-State outputs, enabling efficient bus interfacing and signal isolation. Operating over a 4.75V to 5.25V supply range, it delivers 15mA sink and 12mA source current, making it suitable for driving moderate loads. Its 20-SOIC package is ideal for space-constrained designs. Typical applications include memory buffering, control logic inversion, and 5V bus systems.
- High-Speed 74FCT Logic: Ensures minimal propagation delay for time-critical signal paths.
- 3-State Outputs: Allows direct connection to shared buses for multiplexed data transfer.
- 5V Supply Operation: Compatible with legacy and standard 5V digital systems.
- Inverting Function: Provides signal inversion without additional logic gates.
5V Bus Interfacing
Use the CY74FCT2240TS0C to buffer and invert address or data lines in 5V digital systems, ensuring signal integrity over longer traces.
Memory Address Buffering
Its high-speed 74FCT family performance makes it ideal for buffering address lines to SRAM or DRAM, reducing capacitive loading on the memory controller.
Signal Inversion in Control Logic
Employ the inverting buffer to generate active-low control signals from active-high logic, simplifying glue logic design.
3-State Bus Isolation
The 3-State outputs allow the buffer to be disconnected from a shared data bus, enabling multiple peripherals to communicate without contention.
High-Drive LED Driving
With 15mA sink capability, it can directly drive LEDs or other low-power loads, eliminating the need for external transistors in some applications.
Industrial Control Logic
In industrial controllers operating at 5V, this buffer provides robust signal conditioning and fan-out for PLC I/O modules.
