Overview
The 54L74/BDA is a dual D-type flip-flop with preset and clear functions, belonging to the LVC/LCX/Z series manufactured by Rochester Electronics. It features true outputs and is housed in a PDSO56 package (SSOP-56) with 0.300-inch width. The device operates within a maximum temperature of 85 °C and complies with RoHS standards. It contains two independent flip-flops, each with data, clock, preset, and clear inputs.
Feature Summary
- Dual D-type flip-flop architecture with independent preset and clear control for each stage
- True output configuration providing non-inverted logic states
- Compliant with lead-free manufacturing processes and RoHS directives
Applications
- Digital data storage and latching circuits
- Shift register implementations
- State machine control logic
Procurement Notes
Verify component authenticity through Rochester Electronics certification documents. Confirm package integrity and pin alignment against SSOP-56 specifications. Ensure operational temperature limits are respected within system design parameters. Request test reports validating performance against original manufacturer datasheets.
Selection Notes
Select this component for applications requiring reliable dual D-flip-flop functionality in space-constrained designs. The SSOP-56 package offers suitable pin density for complex logic integration. Verify compatibility with system voltage levels and timing requirements before implementation.
Part Context
Rochester Electronics specializes in lifecycle management of obsolete and hard-to-find semiconductors. The 54L74/BDA represents a recreation or surplus sourcing of legacy logic components, ensuring availability for long-term industrial and military applications where original production has ceased.
Replacement Considerations
Direct substitutes include other 54L74 variants from different manufacturers offering identical pinouts and logical functions. Cross-reference pin assignments and electrical characteristics to ensure functional equivalence without circuit modification.
