CY74FCT163H245CPAC

Overview

The CY74FCT163H245CPAC is a non-inverting bus transceiver from the FCT series, manufactured by Cypress Semiconductor Corp. It features two independent elements, each handling eight bits of data with three-state outputs. The device utilizes a 48-TSSOP package and operates within a voltage range compatible with 3.3V and 5V systems. It provides balanced drive capabilities with specified output currents to ensure signal integrity across high-speed digital interfaces.

Feature Summary

• Non-inverting bidirectional data transfer capability
• Independent control for each transceiver element
• Three-state outputs for bus line management

Applications

• High-speed data bus interfacing
• Memory module data routing
• General-purpose bidirectional level shifting

Procurement Notes

Verify the specific suffix CPAC corresponds to the 48-TSSOP package configuration. Confirm RoHS compliance status as datasheets may vary by production lot. Ensure the supplier provides official Cypress documentation to validate the component authenticity and electrical specifications against the published standard.

Selection Notes

Select this component when dual independent 8-bit non-inverting buses are required in a compact surface-mount form factor. The FCT technology offers speed advantages over older families while maintaining pin compatibility with certain legacy designs. Evaluate power consumption requirements against the specific operating voltage conditions of the target system.

Part Context

This part belongs to the FCT (Fast CMOS Technology) family, designed for high-speed applications. Cypress Semiconductor, now part of Infineon Technologies, produced this series to replace older logic families. The H245 designation indicates a specific variant within the broader 163-series transceiver lineup, focusing on non-inverting functionality.

Replacement Considerations

Check for direct pin-compatible alternatives within the same FCT family or newer generations such as the AUIO series if available. Verify that any substitute maintains the same 48-TSSOP footprint and electrical characteristics to ensure seamless integration without board redesign.
