CY74FCT162245TPACT

Overview

The CY74FCT162245TPACT is a 16-bit bus transceiver from the FCT logic family, manufactured by Texas Instruments. It features bidirectional data transmission with three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device supports an operating temperature range from -40 °C to +85 °C and utilizes a 48-pin TSSOP package.

Feature Summary

• Provides bidirectional data transfer between two 16-bit buses
• Features three-state outputs for effective bus line driving
• Includes common control inputs for direction and output enablement

Applications

• High-speed data routing in computer systems
• Memory buffer applications
• Clock drivers and timing circuits

Procurement Notes

Verify the specific suffix 'PACT' against official documentation to confirm pinout and electrical characteristics match the target design requirements. Ensure compatibility with the intended PCB footprint and thermal management strategy before finalizing procurement decisions.

Selection Notes

Select this component when a 16-bit wide bidirectional interface is required. The FCT technology offers a balance of speed and drive capability suitable for standard TTL loads. Confirm that the TSSOP-48 package fits the available board space and assembly capabilities.

Part Context

This part belongs to the CY74FCT series, which implements Fast CMOS technology. This family provides high-speed performance comparable to older bipolar technologies while maintaining low power consumption typical of CMOS devices. The 162245 variant specifically addresses wide-bus data transfer needs.

Replacement Considerations

Check for direct substitutes such as the CY74FCT16245T or CY74FCT162H245T. Verify that alternative parts maintain identical pin configurations and electrical specifications to ensure seamless integration without redesigning the host circuit.
