Overview
The CY74FCT244DTQC is a high-speed octal buffer and line driver manufactured by Texas Instruments. It features three-state outputs designed for bus-oriented applications, providing low output impedance and high drive capability. The device operates with a single 5V supply and includes input buffers that are compatible with TTL levels. Key electrical characteristics include a propagation delay of typically 3.5ns at 5V and a power dissipation of approximately 60mW. It is housed in a 20-pin SOIC package.
Feature Summary
- Octal buffer and line driver configuration for efficient bus management
- Three-state outputs to prevent signal contention on shared lines
- High-speed performance suitable for demanding digital systems
- TTL-compatible input buffering for broad logic interface support
Applications
- Bus-oriented memory and I/O systems
- Clock drivers and buffered oscillators
- Pattern generators and data registers
Procurement Notes
Verify the exact suffix DTQC against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with your system's voltage requirements and signal integrity needs before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when an octal buffer with three-state control is required for high-speed data transmission. Consider its propagation delay and power consumption relative to other FCT series devices. Verify that the SOIC package fits your PCB layout constraints and thermal management strategy.
Part Context
This part belongs to the FCT (Fast CMOS Technology) family from Texas Instruments, known for combining CMOS low power with TTL speed. The CY74FCT244 variant specifically provides eight non-inverting buffers with three-state outputs, making it a standard choice for bus driving applications in industrial and consumer electronics.
Replacement Considerations
Check for direct pin-to-pin replacements within the same FCT family or newer generations like the LVC series if lower voltage operation is needed. Ensure logical equivalence and electrical specifications match before substituting.
