CD74FCT162244ATMT

Overview

The CD74FCT162244ATMT is a high-speed CMOS bus driver manufactured by Harris Corporation. It features four functional blocks, each providing four bits of true output data. The device operates within a standard voltage range and supports a load capacitance of 50 pF. It utilizes a TSSOP-48 plastic package with a shrink pitch. Key electrical characteristics include a maximum low-level output current of 24 mA and an operating temperature range from -40 °C to 85 °C. The logic family ensures fast propagation delays suitable for demanding digital applications.

Feature Summary

• Bus hold inputs eliminate the need for external pull-up resistors
• Low control type enables efficient signal management
• Three-state outputs with series resistance ensure clean signal transitions

Applications

• High-speed data bus architectures
• Memory interface circuits
• Parallel communication systems

Procurement Notes

Verify the manufacturer designation as Harris Corporation on the component marking. Confirm the specific suffix ATMT corresponds to the TSSOP-48 package variant. Ensure compliance with RoHS standards if required, noting that some legacy documentation may indicate non-compliance status. Cross-reference the JESD-30 code R-PDSO-G48 to validate the physical package dimensions against your PCB footprint requirements.

Selection Notes

Select this component when a quad 4-bit bus driver with true output polarity is required. The FCT series offers superior speed compared to standard TTL equivalents. Consider the 50 pF load capacitance rating for trace length limitations. Verify that the enable logic aligns with the system's control scheme before finalizing the design integration.

Part Context

This part belongs to the FCT (Fast CMOS) logic family, designed for high-performance digital systems. Harris Corporation produced these components before industry consolidations. The 162244 designation identifies it specifically as a 4x4 bit buffer/driver. It serves as a critical interface element in legacy and industrial electronic designs requiring reliable signal buffering.

Replacement Considerations

Compatible substitutes include the IDT 74FCT162244ATPF and Renesas CD74FCT162244ATSM. These alternatives share identical logical functions and pin configurations. Verify package compatibility, as the IDT version uses a TVSOP-48 while the Renesas version uses an SSOP-48. Electrical parameters such as propagation delay and output drive strength should be compared to ensure seamless replacement.
