Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Quality Semiconductor Inc, distinct from other FCT producers. Confirm the specific suffix 'TPAX' corresponds to the required tape and reel packaging format rather than tube or tray configurations. Ensure compliance requirements are checked as the component may not be RoHS certified based on available records.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual 8-bit bidirectional transceiver is required in an SSOP-48 form factor. Consider the 3-state output configuration with series resistors for impedance matching needs. Verify that the operating temperature range of -40°C to 85°C meets the environmental specifications of the target application board.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FCT logic family, which bridges Fast CMOS and Fast TTL performance levels. It serves as a direct replacement for similar 16-bit bus drivers in legacy designs requiring high-speed switching. The 48-pin SSOP package allows for compact surface-mount assembly in dense circuit layouts.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with CY74FCT16244 variants from Cypress or Texas Instruments for pin-compatible alternatives. Verify electrical parameters such as output drive strength and propagation delay against the original design requirements before substitution.
