The IDT74FCT2541TQ from IDT is a single-channel inverting buffer from the 74FCT logic family. Designed for 5V operation (4.75V to 5.25V), it provides a 3-State output with 15mA source and 12mA sink capability. This makes it suitable for high-speed signal inversion and buffering in legacy 5V systems. Its compact 20-SSOP package is ideal for space-constrained designs in industrial control, test equipment, and microprocessor interfaces.
- High-Speed 5V Operation: Optimized for 4.75V to 5.25V systems, ensuring compatibility with legacy TTL logic.
- 3-State Output: Provides bus isolation and prevents contention in shared-signal applications.
- Inverting Function: Allows for signal inversion without additional logic gates, saving board space.
- Compact SSOP Package: The 20-pin SSOP package is suitable for dense PCB layouts.
