Overview
The CY74FCT2244ATQCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features a non-inverting configuration with three-state outputs housed in a 20-pin QSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.6 ns at 5 V, high-level output current of -15 mA, and low-level output current of 12 mA. Static current is specified at 100 nA, with a maximum operating temperature of +85°C.
Feature Summary
- Provides eight-channel buffering with tri-state output capability for bus-oriented architectures
- Features CMOS construction compatible with TTL input and output levels
- Offers low static power consumption suitable for battery-operated systems
Applications
- Clock drivers and buffer circuits
- Memory address decoding
- Carry chains in arithmetic logic units
Procurement Notes
Verify the specific suffix 'ATQC' against the manufacturer's official datasheet to confirm package type, temperature grade, and moisture sensitivity level. Ensure compatibility with existing PCB footprint dimensions for the QSOP-20 variant. Confirm RoHS compliance status through the latest environmental documentation provided by Texas Instruments before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring high-speed signal buffering with minimal propagation delay. The FCT series offers improved switching speeds compared to standard LS logic while maintaining CMOS power efficiency. Consider the 15 mA drive strength for moderate load conditions and verify that the 4.75 V minimum supply voltage aligns with the system's power rail specifications.
Part Context
This part belongs to the CY74FCT2244T family of octal buffers. It serves as a digital logic interface component designed for high-performance applications. The device integrates eight independent buffers into a single package, reducing board space requirements compared to discrete solutions. It is widely used in industrial and consumer electronics where reliable signal transmission is critical.
Replacement Considerations
Check for CY74FCT2244TSOCG4 or CY74FCT2244CTSOC as potential pin-compatible alternatives from the same manufacturer. Verify functional equivalence regarding output drive strength and propagation delay before substitution.
