74FCT162245CTPVG

Overview

The 74FCT162245CTPVG is a dual 8-bit bus transceiver from the Renesas 74FCT series, housed in a 48-pin SSOP package. It operates with a supply voltage range of 4.5V to 5.5V and supports bidirectional data transfer with common direction control. The device features three-state outputs capable of sourcing and sinking 24mA, ensuring robust signal integrity for high-speed digital applications within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission between two 8-bit buses using a single direction control pin.
• Features three-state outputs that isolate the bus when the device is disabled.
• Designed for high-speed operation with low propagation delay characteristics typical of the FCT logic family.

Applications

• High-speed memory buffer interfaces
• Clock distribution networks
• Data bus drivers in industrial control systems

Procurement Notes

Verify the specific suffix 'TPVG' against the manufacturer's current datasheet to confirm package type and material compliance. Ensure the ordering code matches the exact pinout and electrical specifications required for your design, as variations exist within the 74FCT162245 family. Cross-reference with official Renesas documentation to avoid counterfeit components.

Selection Notes

Select this component when a dual 8-bit bidirectional interface is required with standard 5V logic levels. Consider the 48-SSOP package constraints for PCB layout. Evaluate the 24mA drive strength against load requirements. Compare against other FCT variants if lower power or different packaging options are needed for the specific application environment.

Part Context

This part belongs to the Renesas 74FCT logic family, which combines CMOS speed with TTL compatibility. The 74FCT162245 is a specific variant designed for 16-bit wide data paths, effectively acting as two independent 8-bit transceivers. It is widely used in legacy and modern systems requiring reliable 5V signaling with moderate speed performance.

Replacement Considerations

Direct substitutes include the QS74FCT162245TPV from Quality Semiconductor Inc. Verify pin compatibility and electrical parameters before substitution. Other FCT family members may require level shifting or logic adjustments.
