- Integrates 7-bit bidirectional data path with tri-state control
- Utilizes BiCMOS technology for enhanced switching speed and drive capability
Applications
- Parallel printer interface circuits
- IEEE 1284 compatible peripheral connections
- High-speed bidirectional data bus systems
Procurement Notes
Verify component authenticity through authorized distribution channels due to discontinuation status. Confirm package integrity upon receipt, as the 20-SSOP form factor requires careful handling during assembly. Cross-reference datasheet revisions to ensure compatibility with existing system designs before final procurement decisions are made.
Selection Notes
Select this component when designing systems requiring strict adherence to IEEE 1284 protocols. Ensure power supply rails remain within the specified 4.5V to 5.5V window to maintain signal integrity. Consider thermal management requirements associated with BiCMOS logic families in dense PCB layouts.
Part Context
This part belongs to the broader 74ACT logic family, known for CMOS compatibility with TTL input levels. The 1284 variant specifically addresses parallel interface needs, distinguishing it from standard logic gates or memory devices within the same manufacturer portfolio.
Replacement Considerations
Texas Instruments SN74ACT1284DBR is documented as a similar replacement option. Verify pinout compatibility and electrical specifications against original design requirements before substitution.
