Key Features
- 8-bit bidirectional bus transceiver with direction control for reliable data flow management between two bus systems
- High output sink current of 64mA enabling direct drive of TTL and CMOS bus loads without additional buffering
- FCT logic family offering superior speed and lower power than standard FAST TTL with 50pF load capacitance handling
- 20-pin SOIC surface-mount package for compact PCB designs in high-density data bus interface applications
Applications
The CD74FCT245M is widely used as a data bus buffer and interface between microprocessors, memory modules, and peripheral devices in embedded systems and computing boards. Its bidirectional capability with direction control makes it ideal for isolating bus segments, level-shifting between logic families, and driving long PCB traces in industrial control systems and test equipment. The high output drive current enables it to support bus architectures with multiple loads, including ISA, PCI backplane interfaces, and custom backplane designs.

Frequently Asked Questions
What is the output sink current of the CD74FCT245M?
The CD74FCT245M provides a maximum output sink current (IOL) of 64mA, which is significantly higher than standard CMOS logic, allowing it to drive multiple TTL inputs or long PCB traces without signal integrity degradation.
What logic family does the CD74FCT245M belong to?
The CD74FCT245M belongs to the FCT (Fast CMOS Technology) logic family, which combines the speed advantages of bipolar TTL with low CMOS power consumption, making it faster than 74HCT and more power-efficient than 74F TTL logic.
What package is the CD74FCT245M available in?
The CD74FCT245M is packaged in a 20-pin SOIC (Small Outline Integrated Circuit) SMD package, enabling efficient surface-mount PCB assembly and a compact footprint for bus interface circuits in data communication and embedded computing applications.
How does direction control work in the CD74FCT245M?
The CD74FCT245M uses a dedicated direction control pin (DIR) to select data transmission direction: when DIR is HIGH, data flows from A to B, and when DIR is LOW, data flows from B to A, enabling bidirectional bus operation under software or hardware control.
Is the CD74FCT245M compatible with 3.3V logic systems?
The CD74FCT245M operates with a supply voltage of 4.75V to 5.25V and is optimized for 5V TTL logic levels; while its outputs may interface with 3.3V logic inputs in some cases, it is not a true 3.3V device and level translation may be required for full compatibility.
