CY74FCT163245APACT

Overview

The CY74FCT163245APACT is a 16-bit bus transceiver featuring three-state outputs, manufactured by Texas Instruments. It utilizes a 48-pin TSSOP package with dimensions of 0.240 inches and operates within a temperature range of -40°C to +85°C. The device contains two functional units, each handling 8 bits, for a total of 16 bidirectional data paths. It supports common control logic and includes an output short-circuit current rating of 0.024 A.

Feature Summary

• Provides bidirectional data transmission across two independent 8-bit channels.
• Features three-state outputs to facilitate bus line isolation and system flexibility.
• Utilizes FCT logic technology designed for high-speed performance.

Applications

• High-speed data bus architectures requiring bidirectional transfer.
• Memory bus interfaces in computing systems.
• General-purpose digital signal routing applications.

Procurement Notes

Verify the manufacturer designation carefully, as this component is listed under both Cypress Semiconductor Corp and Texas Instruments due to corporate acquisitions. Confirm the specific suffix 'PACT' corresponds to the required 48-TSSOP package and industrial temperature grade (-40 to 85 °C). Ensure compliance requirements are checked against the 'not_compliant' reach status noted in available documentation.

Selection Notes

Select this component when a 16-bit wide bidirectional interface is required with low pin count. The 48-TSSOP package offers a compact solution for dense PCB layouts. Consider the common control input architecture if simultaneous direction switching for all 16 bits is necessary. Verify voltage compatibility with the target system's logic levels before integration.

Part Context

This part belongs to the FCT (Fast CMOS Technology) series, which bridges the performance gap between standard TTL and advanced CMOS logic families. Originally developed by Harris Semiconductor and later acquired by Cypress, then Texas Instruments, these devices are characterized by high drive capability and low power consumption relative to their speed.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific configuration were not identified in the provided source material. Cross-referencing with other FCT series transceivers requires careful verification of pinout compatibility and electrical specifications.
