DM74ALS273N

Overview

The DM74ALS273N is an octal D-type edge-triggered flip-flop belonging to the Advanced Low-power Schottky (ALS) logic family. It features eight independent D-type flip-flops with a common clock and reset, providing non-inverting outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 20-pin SSOP package. Key electrical characteristics 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.

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor products are now managed by onsemi. Confirm that the component meets current RoHS compliance standards and check for any relevant Product Change Notifications regarding packaging or material composition updates before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring octal data storage with advanced low-power Schottky performance levels. Ensure the application environment remains within the specified 0°C to +70°C temperature range and that the power supply voltage stays strictly between 4.5 V and 5.5 V to maintain signal integrity and timing parameters.

Part Context

This part belongs to the DM74ALS series, which represents the Advanced Low-power Schottky logic family known for improved speed and lower power consumption compared to standard LS logic. The 'N' suffix typically denotes a specific package variant, though official documentation lists the SSOP-20 configuration for this model number.

Replacement Considerations

Compatible substitutes include the DM74ALS273MX and DM74ALS273NS. Verify pin compatibility and electrical specifications against the original datasheet before implementation.
