DM74ALS273SJX

Overview

The DM74ALS273SJX is an octal D-type edge-triggered flip-flop manufactured by Fairchild Semiconductor, belonging to the ALS logic series. It features eight independent circuits with single-ended inputs and outputs in a non-inverting configuration. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in an SSOP-20 package. Key electrical parameters include a propagation delay of 15 ns, a high-level output current of -2.6 mA, and a low-level output current of 24 mA. It functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Octal D-type edge-triggered flip-flop architecture providing eight independent data storage elements.
• Advanced Low-power Schottky (ALS) technology ensuring improved AC performance over standard LS counterparts.
• Single-ended input and output configuration with non-inverting logic polarity for direct signal interfacing.

Applications

• Register applications in digital data processing systems
• Shift register configurations for serial-to-parallel data conversion
• Memory interface circuits requiring parallel data latching

Procurement Notes

Verify component authenticity through authorized onsemi or Fairchild channels due to discontinuation status. Confirm package integrity and pin alignment for SSOP-20 compatibility during assembly. Review technical documentation for handling specifications and environmental compliance requirements prior to integration into production workflows.

Selection Notes

Select this component when designing systems requiring octal data storage with ALS speed characteristics. Ensure power supply stability within the 4.5 V to 5.5 V range to maintain specified timing parameters. Consider thermal management capabilities relative to the 0°C to +70°C operational envelope for reliable long-term performance in embedded environments.
