IDT74FCT16952BTPA

Overview

The IDT74FCT16952BTPA is a registered bus transceiver from the FCT series, manufactured by Integrated Device Technology Inc. It features two independent elements, each handling eight bits of data with true (non-inverting) output polarity. The device utilizes CMOS technology and provides three-state outputs for effective bus management. It is housed in a 56-pin TVSOP package. The component operates within a voltage range of 4.5V to 5.5V and supports industrial temperature ranges, ensuring reliable performance in high-speed digital applications requiring registered data transfer.

Feature Summary

• Registered bus transceiver architecture for stable data latching
• Dual eight-bit non-inverting configuration
• Three-state outputs for bidirectional bus control
• CMOS construction for low power consumption

Applications

• High-speed data bus interfaces
• Memory address latching systems
• I/O port buffering
• Bidirectional data transmission circuits

Procurement Notes

Verify the specific suffix 'BTPA' confirms the 56-TVSOP package and lead-free status if required. Confirm RoHS compliance details against the latest manufacturer datasheet, as legacy IDT documentation may vary. Ensure the operating temperature range matches your system's industrial requirements. Cross-reference the pinout diagram with your PCB layout to avoid orientation errors during assembly.

Selection Notes

Select this component when registered data storage is required at the transceiver stage rather than simple buffering. The dual eight-bit structure suits parallel data paths. Consider the TVSOP package constraints for board space. Verify that the three-state capability aligns with your bus arbitration logic. Ensure supply voltage stability within the specified 4.5V to 5.5V window for optimal switching characteristics.

Part Context

This part belongs to the IDT FCT (Fast CMOS) family, designed as a high-speed, low-power replacement for older ABT logic functions. The FCT series emphasizes reduced ground bounce and balanced output drivers. This specific model integrates registration capabilities, distinguishing it from standard transparent latches or simple drivers within the same product line.

Replacement Considerations

Check for direct equivalents such as the IDT74FCT16952CTPV8 or similar FCT series variants with compatible pinouts. Verify functional equivalence regarding registration and tri-state behavior before substitution.
