74AC273SJ

Overview

The onsemi 74AC273SJ is an octal D-type flip-flop belonging to the ACTQ logic series. It features eight non-inverting circuits in a single SOP-20 package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8.5 ns, with high-level and low-level output currents rated at -24 mA and 24 mA respectively. It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• ACTQ logic series technology ensuring fast switching speeds with low power consumption
• Non-inverting output polarity for direct signal transmission without phase reversal
• Robust drive capability supporting high sink and source current requirements

Applications

• High-speed data storage and buffering in digital systems
• Parallel-to-serial conversion circuits

• Register file construction in microprocessor interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check current lifecycle status as availability may vary. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate pinout compatibility with target PCB footprint before integration.

Selection Notes

Select this component when requiring high-speed octal latching with specific 5V logic levels. The ACTQ series offers superior performance compared to standard AC variants. Consider thermal management requirements given the SOP-20 package constraints. Evaluate input signal integrity to ensure reliable clock triggering. Compare against alternative packages if space limitations exist.

Part Context

This part belongs to the broader 74AC273 family of octal D-type flip-flops manufactured by onsemi. It shares functional similarities with other variants like MC74AC273DWG but differs in packaging and specific electrical characteristics. The ACTQ designation indicates optimized performance for advanced applications requiring faster transition times than standard CMOS technologies provide.

Replacement Considerations

MC74AC273DWG serves as a verified substitute offering identical logical functionality in SOIC-WB-20 packaging.
