74FCT621TSOG

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT621TSOG is an octal bus transceiver manufactured by Integrated Device Technology (IDT). It features open-drain outputs and includes a power-off disable function to prevent loading of the bus when the device is unpowered. The component operates within a standard voltage range and supports surface-mount packaging.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bus transceiver architecture with open-drain output configuration
• Power-off disable functionality to isolate the bus during unpowered states
• Compatible with standard CMOS logic families for interface applications

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and command decoders
• Clock drivers
• Buffering and bidirectional data translation between different logic domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TSOG against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with official IDT or Renesas Electronics documentation to confirm availability status and pinout compatibility before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with open-drain capabilities. The power-off disable feature is critical for hot-swap applications or systems where multiple devices share a common bus but may be powered down independently. Verify that the open-drain nature aligns with the pull-up requirements of the target circuit.
