CD74HC243M96G4

Overview

The CD74HC243M96G4 is a high-speed CMOS logic bus transceiver manufactured by Texas Instruments. It features four non-inverting channels and operates within a supply voltage range of 2 V to 6 V. The device utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package with surface-mount technology. It supports an operating temperature range from -55 °C to +125 °C, ensuring reliability in extreme environments. The component is RoHS compliant and lead-free.

Feature Summary

• High-speed CMOS logic technology for efficient signal transmission
• Four-channel non-inverting bus transceiver architecture
• Wide operating voltage range supporting low-power applications
• Extended industrial temperature rating for harsh conditions

Applications

• Data bus isolation between different voltage domains
• Bidirectional data transfer in embedded systems
• Signal buffering in high-speed digital circuits

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with specific environmental standards. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Check the datasheet for precise electrical characteristics relevant to your system's timing constraints. Ensure proper handling procedures are followed due to the surface-mount nature of the component.

Selection Notes

Select this component when bidirectional data transfer is required between buses operating at compatible logic levels. The wide voltage range allows flexibility in system design without level shifting. Consider the propagation delay specifications if high-frequency operation is critical. Verify that the package type fits the available board space and manufacturing capabilities.

Part Context

This part belongs to the Texas Instruments CD74HC series of high-speed CMOS logic devices. The series is known for compatibility with standard CMOS logic families while offering improved speed over older technologies. The M96 suffix typically denotes a specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Direct replacements may include other CD74HC243 variants or SN74HC243 versions depending on packaging preferences. Verify pinout compatibility before substitution. Alternative bus transceivers from other manufacturers may require circuit redesign due to differing electrical characteristics.
