Overview
The CY74FCT374ATSOC is an octal transparent D-type flip-flop register manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features three-state outputs with non-inverting polarity. The device provides high drive capability, delivering -32 mA at high output levels and 64 mA at low output levels. It exhibits a propagation delay of 6.5 ns and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a surface-mount SOIC-20 format, this component integrates eight independent circuits for efficient data storage and bus interfacing applications.
Feature Summary
- Octal D-type flip-flop register architecture providing eight independent data storage elements.
Applications
- Data storage and buffering in digital logic systems
- Bus interface circuitry requiring high drive strength
- Parallel-to-serial conversion modules
Procurement Notes
Verify the specific package variant against project requirements, as suffixes indicate distinct physical footprints. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected component matches the exact ordering number to avoid pinout or electrical specification mismatches during assembly.
Selection Notes
Select this component when an octal register with robust current drive capabilities is required. The FCT series ensures compatibility with TTL input levels while maintaining CMOS output characteristics. Evaluate the 6.5 ns propagation delay against system timing constraints to ensure signal integrity is maintained across the operating temperature range.
Part Context
This part belongs to the CY74FCT374T family of octal registers. Variants such as CY74FCT374ATQCT and CY74FCT374TSOCT share identical logical functionality but differ in packaging styles, including SSOP and SOIC configurations. All variants maintain consistent electrical parameters and operational specifications defined by the base model.
