Supplier Device Package 24-SSOP (0.154", 3.90mm Width)

The IDT74FCT2543TQ is a high-speed, non-inverting transceiver from the FCT logic family. Designed for 5V systems (4.75V to 5.25V), it provides bidirectional data transfer with 3-State outputs to prevent bus contention. With a strong output current of 15mA/12mA, it can drive heavy capacitive loads, making it ideal for memory interfacing, backplane communication, and general bus buffering. Housed in a compact 24-SSOP package, it is a reliable choice for demanding digital systems.

  • High-Speed FCT Logic: Optimized for fast propagation delays, critical for high-performance computing and communication systems.
  • 3-State Outputs: Allows multiple devices to share a common bus safely, preventing data corruption.
  • Strong Drive Capability (15mA/12mA): Ensures signal integrity when driving long traces or multiple loads.
  • Wide 5V Supply Range (4.75V-5.25V): Compatible with standard 5V TTL systems, simplifying power design.

High-Speed Bus Interfacing

Use the IDT74FCT2543TQ to interface between two high-speed 5V data buses. The 3-State outputs prevent bus contention, and the FCT family's fast propagation delay ensures minimal signal latency.

Bidirectional Data Buffering

In systems where data flows in both directions, this transceiver provides the necessary buffering. Its non-inverting nature preserves signal polarity, simplifying logic design.

Memory Address/Data Driving

Drive memory address or data lines with the high current capability (15mA/12mA). This ensures reliable signal integrity even with multiple memory chips connected to the bus.

Backplane Communication

In rack-mounted systems, this transceiver can drive signals across a backplane. The 3-State outputs allow multiple boards to share the same bus without interference.

Level Shifting (5V to 5V TTL)

While not a level shifter, it regenerates and strengthens 5V TTL signals, ensuring clean logic levels over longer traces or cables.

Industrial Control I/O

For industrial controllers operating at 5V, this IC provides robust buffering for I/O modules, protecting the main controller from external noise and loading.
