Overview
The SN74ACT11273DWR is an octal transparent D-type flip-flop manufactured by Texas Instruments. It belongs to the 74ACT logic series and features eight independent D-type flip-flops with positive-edge triggering. The device operates within a supply voltage range of 4.5 V to 5.5 V, ensuring compatibility with standard CMOS and TTL logic levels. It exhibits a propagation delay of 8.5 ns at 5 V and maintains a static current of 8 uA. The outputs provide low-level output currents of 24 mA and high-level output currents of -24 mA. Designed for surface-mount applications, it is housed in a SOIC-24 package and supports operating temperatures from -40°C to +85°C.
Feature Summary
- Octal configuration providing eight independent positive-edge triggered D-type flip-flops for parallel data storage
- Transparent latch architecture allowing direct data passage when enabled, facilitating efficient bus interfacing
- CMOS-compatible input and output characteristics with robust drive capabilities for standard logic loads
Applications
- Parallel-to-serial data conversion circuits
- High-speed buffer memory interfaces
- Register stages in digital signal processing systems
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm package type and reel specifications. Ensure that the procurement channel provides valid traceability for the Texas Instruments brand. Cross-reference the component marking with official datasheet pinouts to prevent installation errors during surface-mount assembly processes.
Selection Notes
Select this component when designing systems requiring octal data storage with positive-edge triggering. The ACT series offers superior speed compared to older HC or HCT variants while maintaining CMOS power efficiency. Consider the SOIC-24 footprint for PCB layout constraints and verify that the 5V supply environment matches the specified operating voltage range for optimal performance.
Part Context
This part is a member of the Texas Instruments 74ACT family, which bridges the performance gap between standard CMOS and Low-Power Schottky TTL technologies. The 74ACT11273 variant specifically addresses applications needing multiple synchronized data latches. It complements other octal logic devices like the 74ACT11373, differing primarily in internal triggering mechanisms and transparency behavior.
Replacement Considerations
The 74ACT11273DBR serves as a verified alternative offering identical logical functionality in a 24-SSOP package. Designers must adjust PCB footprints and soldering profiles when substituting the SOIC-24 variant with the SSOP version.
