74LVC623ADB-Q100J

Overview

The 74LVC623ADB-Q100J is an octal bus transceiver manufactured by Nexperia, operating within the LVC logic series. It features dual enable inputs and three-state outputs, housed in a PDSO20 package. The device supports a supply voltage range of 1.65 V to 3.6 V and operates across a temperature range of -40°C to +125°C. Key electrical parameters include a propagation delay of 19 ns and a maximum power dissipation of 500 mW.

Feature Summary

• Octal bus transceiver architecture with independent direction control
• Dual enable functionality for flexible signal routing
• Automotive qualification compliant with AEC-Q100 standards

Applications

• Automotive electronic systems requiring robust data transfer
• High-density memory interface circuits
• Industrial control systems with wide temperature requirements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix matches the required automotive grade and packaging format. Check current lifecycle status as end-of-life notifications may affect long-term availability. Ensure compliance with RoHS directives for your target market.

Selection Notes

Select this component when an octal transceiver with dual enable controls is required for automotive or industrial applications. Verify that the 1.65 V to 3.6 V supply range aligns with system power rails. Ensure the SOIC-20 or SSOP-20 package fits the PCB layout constraints. Confirm that the 19 ns propagation delay meets the timing specifications of the connected interfaces.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. It is functionally similar to other octal bus transceivers but distinguished by its automotive qualification and dual enable structure. The Q100 suffix indicates adherence to strict automotive reliability standards set by the Automotive Electronics Council.

Replacement Considerations

Check for direct cross-references from manufacturers like NXP or Texas Instruments offering identical pinouts and electrical characteristics. Verify that any substitute maintains the same AEC-Q100 qualification level and package dimensions to ensure mechanical compatibility.
