SN74ALS528N

Comparators Overview

The SN74ALS528N is an 12-bit identity comparator from the Texas Instruments ALS logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a PDIP-16 package. The device provides inverted outputs for equality detection, with a propagation delay specified at 20 ns. It supports through-hole mounting and functions reliably across an operating temperature range of 0°C to +70°C.

Comparators Feature Summary

• Performs 12-bit identity comparison with inverted output indication
• Utilizes Advanced Low-Power Schottky (ALS) technology for optimized performance
• Designed for standard TTL-compatible logic levels

Comparators Applications

• Digital data path equality verification
• Address decoding in memory systems
• Control logic validation circuits

Comparators Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-16 through-hole package variant. Confirm the manufacturer source is Texas Instruments or authorized distributors. Check RoHS compliance status as indicated in official documentation. Ensure the component matches the 12-bit specification rather than other bit-width variants in the family.

Comparators Selection Notes

Select this component when a 12-bit wide equality check is required with low power consumption. The ALS series offers a balance between speed and power dissipation suitable for general-purpose digital applications. Consider the PDIP-16 package if through-hole assembly is mandated by the PCB design constraints.

Comparators Part Context

This part belongs to the SN74ALS528 family of comparators. It serves as a specialized logic IC for determining if two 12-bit binary words are identical. The device integrates multiple input stages into a single compact package, reducing board space compared to discrete gate implementations.

Comparators Replacement Considerations

SN74ALS528NSR is the reel-packaged equivalent of this through-hole component.
