74FCT16245ATPVG

Overview

The IDT74FCT16245ATPVG is a 16-bit bidirectional bus transceiver from the 74FCT logic series, manufactured by Integrated Device Technology. It features two independent 8-bit channels with true outputs and TTL-compatible input/output levels. The device operates within a supply voltage range of 2.7V to 3.6V or 4.5V to 5.5V. It utilizes a 48-pin SSOP surface-mount package. Key electrical specifications include a maximum propagation delay of 5ns at 50pF load capacitance, a high-level output current of -32mA, and a low-level output current of 64mA. The component supports an extended commercial operating temperature range from -40°C to +85°C.

Feature Summary

• Provides high-drive capability with strong sink and source currents for reliable signal integrity
• Offers power-off disable functionality to permit live insertion without bus contention
• Ensures low leakage and high ESD protection for robust operation in sensitive environments

Applications

• High-speed data bus architectures requiring bidirectional transfer
• Memory bus interfaces in computing systems
• Industrial control systems with mixed voltage domains

Procurement Notes

Verify the specific suffix 'TPVG' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the selected variant matches the required voltage domain (3.3V or 5V) as defined in the electrical characteristics table. Cross-reference the ordering code with the latest Renesas or IDT documentation to avoid obsolete stock issues.

Selection Notes

Select this component when a 16-bit bidirectional interface with TTL compatibility is required. The FCT technology provides a faster replacement for older ABT functions while maintaining CMOS power efficiency. Consider the 48-pin SSOP package constraints for PCB layout. Verify that the system's I/O requirements align with the specified -32mA/64mA drive strengths.

Part Context

This part belongs to the 74FCT family of Fast CMOS logic devices. It serves as a direct functional upgrade for legacy 74ABT series components. The device integrates direction control and common enable signals to manage data flow between two 8-bit buses efficiently.

Replacement Considerations

Cross-reference with CY74FCT16245ATPAC from Cypress/Texas Instruments for pin-compatible alternatives. Check IDT74FCT16245ETE for Cerpack package variations if through-hole mounting is required.
