CY74FCT162245ATPVC

Overview

The CY74FCT162245ATPVC is a 16-bit bidirectional bus transceiver manufactured by Cypress Semiconductor. It operates within a voltage range of 4.5V to 5.5V and supports data transfer rates up to 33MHz. The device features balanced output drivers with ±24mA drive capability, designed to reduce system switching noise. It includes power-off disable outputs to permit live insertion without bus contention. The component is housed in a 48-pin TSSOP package and functions as a high-speed, low-power logic interface.

Feature Summary

• Balanced output drivers providing symmetric current sourcing and sinking capabilities
• Power-off disable functionality enabling safe live insertion into active systems
• High-current drive design for robust signal transmission across buses

Applications

• High-speed bidirectional data bus interfaces
• Memory-to-processor communication links
• System-level I/O expansion modules

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments also produces equivalent FCT series devices under similar part numbers. Confirm the specific suffix 'ATPVC' matches the required temperature grade and package variant. Ensure compatibility with existing board layouts for the 48-pin TSSOP footprint before procurement.

Selection Notes

Select this component when balanced drive strength is required to minimize ground bounce and switching noise in high-speed digital designs. It serves as a direct replacement for standard FCT162245 variants where live insertion protection is necessary. Consider the 48-pin TSSOP package constraints during PCB layout planning.

Part Context

This device belongs to the FCT (Fast CMOS) family of logic components, known for combining CMOS low power consumption with TTL-compatible speed. It is part of a broader portfolio of bus transceivers used for managing data flow between different voltage domains or logic families in complex electronic systems.

Replacement Considerations

Public confirmed substitute part numbers include PI74FCT162245T from Diodes Incorporated.
