CD74FCT541M

Overview

The CD74FCT541M is an octal bus driver manufactured by Harris Corporation, belonging to the FCT logic series. It features eight true outputs and operates with a supply voltage range of 4.5V to 5.5V. The device utilizes CMOS technology and provides three-state outputs controlled by low-active enable signals. Packaged in a 20-pin Small Outline Package (SOP), it supports surface-mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides eight non-inverting data paths for bus transmission
• Features dual output enable controls for flexible direction management
• Incorporates bus hold inputs to maintain signal states without external pull-up resistors

Applications

• Memory map buffering in computer systems
• Clock drivers and buffer circuits
• Bus-oriented transmissions requiring high-speed data transfer

Procurement Notes

Verify component authenticity through official Harris Corporation channels or authorized distributors. Confirm package integrity and pin alignment prior to assembly. Ensure storage conditions comply with moisture sensitivity level requirements to prevent internal damage during soldering processes.

Selection Notes

Select this component when designing systems requiring fast switching speeds and low power consumption. The FCT series compatibility ensures interoperability with other Fast CMOS devices. Consider the SOP-20 footprint constraints and thermal dissipation capabilities relative to the specific PCB layout design requirements.

Part Context

This part belongs to the Harris CD74FCT family of high-speed CMOS logic devices. It serves as a standard octal buffer solution within the broader portfolio of bus transceivers and drivers designed for digital signal processing applications requiring reliable data isolation and transmission control.

Replacement Considerations

Cross-reference with Texas Instruments CY74FCT541ATQCT for equivalent functionality. Verify pinout compatibility and electrical specifications before substituting components in existing designs.
