Overview
The CY74FCT377TQCT is an octal D-type flip-flop register from the Texas Instruments FCT logic series, housed in a 20-SSOP surface-mount package. It features eight edge-triggered D-type flip-flops with individual data inputs and a common buffered clock input. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a wide operating temperature range from -40°C to +85°C. Key electrical specifications include a propagation delay of 5.2 ns, a high-level output current capability of -32 mA, and a low-level output current capability of 64 mA.
Feature Summary
- Contains eight edge-triggered D-type flip-flops for simultaneous data loading via a common clock.
Applications
- Address and data synchronization
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific order matches the CY74FCT377TQCT designation, including the SSOP-20 package and industrial temperature rating. Review the official datasheet for handling instructions related to moisture sensitivity and electrostatic discharge protection during assembly.
Selection Notes
Select this component when an octal register with high drive strength is required. The 64 mA sink current capability distinguishes it from lower-drive variants. Ensure the design accommodates the 4.75 V to 5.25 V supply requirement and utilizes the clock-enable feature for controlled data latching. Verify pin compatibility if replacing older FCT devices.
Part Context
This part belongs to the CY74FCT377T family of 8-bit registers. It is designed for high-speed digital applications requiring reliable data storage and transfer. The FCT series combines CMOS speed with TTL-compatible input levels, facilitating integration into mixed-logic systems.
