CY74FCT377ATSOCTG4

Overview

The CY74FCT377ATSOCTG4 is an octal D-type flip-flop register from the FCT logic family, manufactured by Texas Instruments. It features eight edge-triggered D-type flip-flops with individual data inputs and a common buffered clock input. The device includes a clock-enable function for address and data synchronization. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 5.2 ns. Output drive capabilities include -32 mA source current and -12 mA sink current. The component is housed in a 20-SOIC package and is designed for partial-power-down applications using Ioff circuitry.

Feature Summary

• Contains eight edge-triggered D-type flip-flops with individual data inputs and a common buffered clock.
• Includes clock-enable functionality to facilitate address and data synchronization.
• Supports partial-power-down mode operation through integrated Ioff circuitry that disables outputs.

Applications

• Address and data synchronization in digital systems
• Octal register implementations requiring edge-triggered storage
• Partial-power-down applications utilizing Ioff output disabling

Procurement Notes

Verify the specific suffix 'A' against official documentation, as standard variants typically specify different drive currents. Confirm RoHS compliance status via the manufacturer's datasheet. Check availability status directly with authorized distributors, as this part number may be discontinued or subject to limited stock conditions. Ensure the SOIC-20 package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when an octal register with edge-triggered operation and clock enable is required. Compare drive current specifications against load requirements, noting potential variations between 'T' and 'A' suffixes. Verify compatibility with TTL input levels and ensure the operating temperature range meets system environmental constraints. Consider Ioff support if partial power-down functionality is necessary for the application.

Part Context

This component belongs to the FCT logic series, which combines CMOS density with TTL-compatible speeds. The CY74FCT377 variant specifically provides octal storage capabilities. Related parts in the family include the CY74FCT377T with higher drive currents and other registers like the CY74FCT374. The G4 suffix indicates lead-free packaging compliant with RoHS standards.

Replacement Considerations

Public confirmed substitute part numbers: CY74FCT377CTSOCTG4, CY74FCT377TQCT. Note that the 'T' suffix variant offers different output drive currents (-64 mA sink/-32 mA source) compared to the standard description. Verify pinout and electrical characteristics match the design requirements before substitution.
