74FCT16245ATPAG

Overview

The 74FCT16245ATPAG is a dual 8-bit bus transceiver from the FCT/PCT-CMOS logic family, manufactured by Renesas Electronics. It operates on a single 5 V power supply and features bidirectional data flow controlled by a common direction signal. The device utilizes a 48-pin TSSOP plastic package with a shrink pitch. It provides three-state outputs for effective bus line management. The component supports an operating temperature range from -40 °C to +85 °C and exhibits a propagation delay of 4.6 ns at nominal supply voltage.

Feature Summary

• Dual 8-bit configuration enabling simultaneous transmission across two independent channels
• Bidirectional data transfer capability managed by a unified control input
• Three-state output architecture designed for efficient multi-driver bus isolation

Applications

• High-speed memory interface implementations
• Microprocessor-based system data routing
• Control signal distribution networks

Procurement Notes

Verify the specific suffix 'TPAG' against official Renesas documentation to confirm the exact tape-and-reel packaging configuration and pin compatibility. Ensure the order matches the required industrial temperature grade and RoHS compliance status as defined in the current datasheet revision. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement.

Selection Notes

Select this component when a dual-channel, high-speed CMOS solution is required for 5 V systems. The FCT series offers superior speed compared to standard LS logic while maintaining CMOS power efficiency. Verify that the 48-pin TSSOP footprint fits the target PCB layout constraints. Confirm that the bidirectional nature aligns with the system's data flow requirements and that the drive strength meets the load capacitance specifications.

Part Context

This device belongs to the 74FCT16245T series of bus transceivers. It serves as a bridge between internal system buses and external peripheral devices. The FCT technology combines the speed of bipolar circuits with the low power consumption of CMOS. This specific variant is designed for applications requiring reliable data transfer in noisy environments typical of industrial and commercial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the same FCT family or cross-manufacturer equivalents like IDT variants. Ensure replacement parts maintain identical voltage levels, package dimensions, and electrical characteristics such as propagation delay and output drive current.
