74ACTQ646SPC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ACTQ646SPC is an octal transceiver and register featuring non-inverting logic with three-state outputs. Designed for high-speed applications, it operates within a supply voltage range of 2V to 6V. The device utilizes CMOS technology and is housed in a 24-pin Dual In-Line Package (DIP). It supports a maximum operating frequency of 80MHz at a nominal 5V supply. The component functions as both a bus-holding transceiver and a register, providing versatile data handling capabilities for digital systems.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SPC' against current manufacturer documentation to confirm package type and pinout compatibility. Confirm RoHS compliance status as historical records may vary. Check for obsolescence notices from onsemi, as Fairchild's semiconductor division has undergone corporate transitions. Ensure lead times are validated directly with authorized distributors due to potential lifecycle changes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal, non-inverting transceiver with three-state outputs is required for 5V or lower logic systems. Consider the 74ACT series specifications for speed and power consumption characteristics. Verify that the DIP-24 package fits the target PCB layout constraints. Compare against standard 74AC646 variants if bus-holding functionality is not strictly necessary.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACTQ Quiet Series, designed for low-noise performance in high-speed digital applications. The 74ACTQ646 serves as an octal transceiver/register, bridging the gap between standard logic speeds and advanced system requirements. It is manufactured by Fairchild Semiconductor, now part of onsemi, utilizing CMOS technology for efficient operation.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AC646SPC is a related variant within the same family but lacks the specific Quiet Series attributes. Verify functional equivalence before substitution. Consult official cross-reference guides for exact pin-compatible alternatives if the 74ACTQ646SPC is unavailable.
