DM74ALS273MSAX

Overview

The DM74ALS273MSAX is an octal D-type flip-flop manufactured by onsemi, belonging to the Advanced Low-power Schottky (ALS) logic series. It features eight non-inverting outputs triggered on the positive edge of the clock signal. The component is housed in a 20-pin SSOP package and supports single-ended inputs and outputs. Designed for surface-mount applications, it operates within standard TTL voltage ranges. This specific part number indicates a tape-and-reel packaging configuration intended for automated assembly processes.

Feature Summary

• Octal D-type flip-flop architecture with eight independent data storage elements
• Positive-edge triggering mechanism for synchronous data capture
• Non-inverting output polarity providing direct logical state representation
• Advanced Low-power Schottky technology ensuring high-speed operation with reduced power consumption

Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Data buffering and latching operations
• State machine output storage

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation to confirm availability status and packaging type. The DM74ALS273MSA series may have multiple variants; ensure the specific MSAX suffix matches the required reel quantity and handling specifications. Confirm RoHS compliance details and lifecycle status directly through authorized distributors or the manufacturer's current product announcements prior to procurement planning.

Selection Notes

Select this component when high-speed switching with low power dissipation is required in space-constrained designs. The ALS family offers superior speed compared to standard LS logic while maintaining lower power than AS series. Ensure the design accommodates the SSOP-20 footprint and thermal requirements. Verify that the system voltage levels align with the ALS logic family specifications for reliable noise margins and signal integrity across the operating temperature range.

Part Context

This device is part of the broader 74ALS273 family of octal flip-flops produced by onsemi. It shares functional compatibility with other manufacturers' ALS273 equivalents but differs in specific electrical characteristics and packaging options. The DM prefix typically denotes a specific manufacturing line or material composition variant within the onsemi portfolio, distinguishing it from MC or MM prefixed parts.

Replacement Considerations

Public confirmed substitute part numbers include SN74ALS273DW from Texas Instruments and DM74ALS273M from National Semiconductor. These alternatives share the same logical function and pinout but may exhibit variations in propagation delay and output drive strength. Always consult individual datasheets for precise electrical parameter comparisons before substitution.
