CD74FCT162245CTMT

Overview

The CD74FCT162245CTMT is a bus transceiver from the FCT series manufactured by Harris Corporation. It features two functional blocks, each handling eight bits of data, resulting in a dual 8-bit configuration. The device utilizes CMOS technology and provides true output polarity. It is housed in a 48-pin plastic dual small-outline package (PDSO48). Key electrical characteristics include a load capacitance of 50 pF and a maximum low-level output current of 0.024 A. The component operates within an extended commercial temperature range spanning from -40 °C to +85 °C.

Feature Summary

• Bus hold inputs eliminate the need for external pull-up resistors
• Low input and output leakage currents
• High-speed operation suitable for replacing ABT functions

Applications

• High-speed data bus architectures
• Memory interface circuits
• Bidirectional data buffering systems

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities when sourcing this component. Confirm the specific suffix CTMT corresponds to the intended tape-and-reel packaging format. Ensure compatibility with existing system voltage levels and signal integrity requirements before integration into final designs.

Selection Notes

Select this component for applications requiring bidirectional data transfer with high speed and low power consumption. The FCT series offers performance comparable to older technologies while maintaining CMOS advantages. Consider the 48-pin package constraints and thermal management needs for the specified operating temperature range during board layout planning.

Part Context

This part belongs to the Harris FCT logic family, designed as fast CMOS replacements for earlier transistor-transistor logic standards. The CD74FCT162245 variant specifically addresses bidirectional communication needs. Harris Corporation was a primary producer of these components before industry consolidations affected the brand's independent manufacturing status.

Replacement Considerations

Cross-reference with IDT74FCT162245 variants for equivalent functionality from Integrated Device Technology. Verify pinout compatibility and electrical specifications against alternative manufacturers' datasheets to ensure seamless substitution in existing circuit designs.
