CD74FCT163244CSM

Overview

The CD74FCT163244CSM is a CMOS bus driver from the FCT series manufactured by Harris Corporation. It features four functional drivers with true outputs and operates within a voltage range up to 5.5 V. The device utilizes a 48-pin SSOP package (SSOP48,.4) and supports an operating temperature range from -40 °C to 85 °C. Key electrical characteristics include a maximum low-level output current of 0.024 A, a load capacitance of 50 pF, and three-state outputs with series resistors. Control is managed via a low-active enable signal.

Feature Summary

• Bus hold inputs eliminate the need for external pull-up resistors
• Three-state outputs with integrated series resistors
• Low-active enable control logic

Applications

• High-speed data bus buffering
• System memory interface driving
• Control signal distribution in embedded systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as documentation indicates non-compliance. Ensure the specific SSOP48 package variant matches design requirements. Validate temperature ratings against operational environment constraints before integration.

Selection Notes

Select this component for applications requiring high-speed CMOS bus driving with integrated bus hold functionality. The four-channel configuration suits parallel data paths. Verify that the low-active enable polarity aligns with system control logic. Consider the 50 pF load capacitance rating when designing trace lengths and termination strategies.

Part Context

This part belongs to the Harris FCT logic family, designed for fast CMOS performance. It shares architectural similarities with other FCT bus drivers like the CD74FCT162H244TMT but differs in pinout and specific feature sets such as bus hold inputs. The CSM suffix denotes the specific SSOP48 packaging configuration used for surface-mount assembly.

Replacement Considerations

Cross-reference with CD74FCT162H244TMT for similar bus driver functions. Verify pin compatibility and electrical specifications before substitution. Note that package differences may require PCB layout adjustments.
