CD74FCT16652TSM

Overview

The CD74FCT16652TSM is a dual 8-bit registered bus transceiver from the FCT series, manufactured by Harris Corporation. It features non-inverting outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 56-pin SSOP package and supports 3-state output characteristics. Designed for CMOS technology, it includes independent output enable controls for each direction, facilitating efficient data transfer in high-speed digital systems.

Feature Summary

• Dual 8-bit registered bus transceiver architecture
• Non-inverting output polarity with 3-state capability
• Independent output enable control for bidirectional operation

Applications

• High-speed data bus interfaces
• Memory buffer applications
• Bidirectional data transmission systems

Procurement Notes

Verify component authenticity through authorized Harris Corporation distributors or certified suppliers. Confirm RoHS compliance status as documentation indicates lead-free variants exist. Ensure the 56-pin SSOP package matches design requirements. Validate operating temperature range specifications against system environmental constraints before procurement.

Selection Notes

Select this component for applications requiring registered bidirectional data transfer with non-inverting logic. The dual 8-bit configuration suits wide bus architectures. Consider the 56-pin SSOP footprint for PCB layout compatibility. Verify power supply stability within the 4.5 V to 5.5 V range to ensure proper 3-state operation and signal integrity.

Part Context

This part belongs to the Harris FCT (Fast CMOS) logic family, designed for high-speed performance. It serves as a registered transceiver, distinguishing it from simple buffers. The TSM suffix denotes the specific SSOP package variant. As a legacy Harris product, it may be superseded by newer iterations from acquired entities like Fairchild Semiconductor.

Replacement Considerations

Check for direct pin-compatible equivalents from Fairchild Semiconductor, which acquired Harris Logic products. Verify if updated FCT series versions maintain the same 56-SSOP form factor and electrical specifications. Ensure any substitute retains the registered dual 8-bit transceiver functionality.
