CY74FCT574TQC

Overview

The CY74FCT574TQC is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features TTL-compatible inputs. The device provides non-inverting logic with a maximum propagation delay of 10 ns. Output drive capabilities include -32 mA for high-level and 64 mA for low-level currents. It is housed in a 20-pin QSOP package and supports surface-mount installation. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

Octal edge-triggered D-type flip-flop architecture with three-state outputs
TTL-compatible input structure for direct interfacing
High-drive output capability supporting heavy capacitive loads

Applications

Parallel data storage in digital systems
Bus interface buffering applications
Clock domain synchronization circuits

Procurement Notes

Verify the manufacturer designation on the datasheet, as Texas Instruments produces this part under the Cypress Semiconductor product lineage. Confirm the specific package suffix corresponds to the required QSOP-20 form factor. Ensure compliance with RoHS directives if environmental standards are mandatory for the assembly process. Cross-reference the ordering suffix to confirm moisture sensitivity levels and reel specifications.

Selection Notes

Select this component when an octal register with tri-state control is required for bus architectures. The TTL-compatible inputs simplify interface design with legacy logic families. The high current drive ratings make it suitable for driving multiple loads or long traces. Consider the QSOP package dimensions for PCB layout constraints and thermal management requirements during integration.

Part Context

This device belongs to the FCT (Fast CMOS Technology) logic family, designed for high-speed performance with CMOS power efficiency. The CY74FCT574 series serves as a standard solution for registering eight bits of data. It bridges the gap between older TTL designs and modern CMOS requirements, offering speed comparable to LS-TTL while maintaining lower power consumption typical of CMOS devices.
