- Register file implementations in digital systems
- Buffering and latching applications in microprocessor interfaces
Flip Flops Procurement Notes
Verify the specific suffix 'DBR' corresponds to the SOIC-20 surface-mount package and tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Cross-reference datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement specifications.
Flip Flops Selection Notes
Select this component when an octal register with three-state outputs is required for TTL-compatible logic families. Consider the 10.5 ns propagation delay and 24 mA drive strength for timing and load analysis. Ensure the SOIC-20 footprint fits the PCB layout constraints compared to through-hole alternatives like the N variant.
Flip Flops Part Context
This part belongs to the SN74ACT series, representing advanced CMOS technology compatible with TTL inputs. It offers improved speed over standard 74AC devices while maintaining similar power consumption characteristics. The octal configuration allows for efficient handling of wide data buses in parallel processing environments.
Flip Flops Replacement Considerations
SN74ACT564DWR (same logic, different reel quantity), SN74ACT564DW (tube packaging), SN74ACT564N (through-hole DIP). Verify package compatibility and thermal performance when substituting.
