SN74ALS573CNSR

Overview

The SN74ALS573CNSR is an octal transparent D-type latch manufactured by Texas Instruments within the ALS logic series. It features eight non-inverting outputs and operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device utilizes a 20-pin NS package for surface-mount installation. Key electrical specifications include a propagation delay of 14 ns, a low-level output current capability of 32 mA, and a high-level output current of -2.6 mA. It functions within a commercial temperature range of 0°C to +70°C with a typical operating supply current of 24 mA.

Feature Summary

• Provides eight parallel data paths through transparent D-type latching architecture
• Delivers strong low-level sink current capacity for driving heavy loads
• Supports standard surface-mount assembly processes via compact package format

Applications

• Parallel data buffering in digital systems
• Registering input signals for microprocessor interfaces
• Temporary storage of address or data buses

Procurement Notes

Verify the specific suffix 'CNSR' against official manufacturer documentation to confirm pinout compatibility and operational limits. Ensure the component meets required environmental standards for the intended deployment environment. Cross-reference datasheet parameters with system requirements before integration.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and robust drive capabilities within the 5V logic family. Consider the ALS series characteristics for applications demanding lower power consumption than standard TTL while maintaining higher speed performance. Evaluate thermal management needs based on the specified operating temperature range.

Part Context

This part belongs to the SN74ALS573 family of octal latches produced by Texas Instruments. The ALS designation indicates Advanced Low-power Schottky technology, which offers improved speed-to-power product compared to earlier generations. The NS suffix identifies the specific physical package type used for board mounting.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the SN74ALS573DW or SN74ALS573N depending on package preference. Verify that any substitute maintains identical pin configurations and electrical characteristics to ensure seamless circuit integration.
