CY74FCT574TSOC

Overview

The CY74FCT574TSOC is an octal edge-triggered D-type flip-flop with 3-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 high drive capability with a low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay is specified at 10 ns. It functions in non-inverting mode and is housed in a 20-SOIC surface-mount package, supporting an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent edge-triggered D-type flip-flops for parallel data storage.

Applications

• Parallel data buffering in digital systems
• Register stages in microprocessor-based designs
• I/O interface circuits requiring tri-state control

Procurement Notes

Verify the specific suffix 'TSOC' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the design accommodates the 20-SOIC package dimensions and thermal requirements for the specified operating temperature range. Cross-reference ordering information directly with Texas Instruments documentation to avoid discrepancies.

Selection Notes

Select this component when an octal register with high-current drive and 3-state output control is required. It is suitable for applications needing TTL input compatibility and fast propagation speeds within the FCT logic family. Consider the SOIC-20 package constraints and power supply stability between 4.75 V and 5.25 V during circuit design.

Part Context

This part belongs to the CY74FCT574T series of octal edge-triggered D-type flip-flops. It is distinct from buffer or transceiver variants like the CY74FCT541 or CY74FCT2245 due to its internal latching functionality. The TSOC suffix denotes the specific plastic small-outline package type used for surface-mount assembly.
