CD74FCT162240ATMT

Overview

The CD74FCT162240ATMT is a CMOS bus driver from the FCT series manufactured by Harris Corporation. It features four independent functions, each handling four bits of data with inverted output polarity. The device utilizes a 48-pin TSSOP package and operates within a temperature range of -40°C to 85°C. Key electrical characteristics include a maximum low-level output current of 0.024 A and a load capacitance of 50 pF. The outputs are three-state with series resistors, controlled by a low-enable signal.

Feature Summary

• Incorporates bus hold inputs to eliminate the need for external pull-up resistors
• Provides three-state outputs integrated with series resistors
• Features inverted output polarity for logical inversion applications

Applications

• High-speed data bus buffering in computer systems
• Clock distribution networks requiring signal inversion
• Memory interface circuits utilizing bus hold functionality

Procurement Notes

Verify the specific manufacturer source, as Harris Corporation's semiconductor assets were acquired by Texas Instruments. Confirm that the part number corresponds to the original Harris production or the subsequent TI continuation. Ensure the TSSOP-48 package variant matches the required PCB footprint and that the operating temperature range meets system environmental specifications.

Selection Notes

Select this component when inverted logic levels are required for bus driving applications. The inclusion of bus hold inputs simplifies design by removing external pull-up components. Verify compatibility with the target voltage supply and ensure the three-state control logic aligns with the system's enable requirements. Consider the thermal performance of the TSSOP package for the intended application environment.
