SN74ALS653NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS653NT is an octal bus transceiver and register manufactured by Texas Instruments. It belongs to the ALS logic series and features three-state outputs with open-collector capability. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. It provides a propagation delay of 64 ns, with low-level output current of 24 mA and high-level output current of -15 mA. Designed for surface-mount applications, it is housed in an SOIC-24 package and functions within a temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NT' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOIC-24 form factor. Confirm that the open-collector output characteristics align with the target circuit design requirements before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with internal registration is required for system buses. The ALS series offers a balance of speed and power consumption suitable for standard 5V logic environments. Consider the open-collector output option if wired-AND configurations or higher voltage tolerance on outputs are necessary for the application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN74ALS653 family of octal bus transceivers. It serves as a registered buffer for bidirectional data flow. The ALS technology ensures faster switching speeds compared to standard LS logic while maintaining lower power dissipation than AS series devices, making it suitable for general-purpose digital logic applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-to-pin replacements within the same ALS family, such as other SN74ALS653 variants with different suffixes. Verify functional equivalence regarding the registered transceiver architecture and output drive capabilities before substituting.
