M74HC368RM13TR

Overview

The M74HC368RM13TR is a high-speed CMOS hex bus driver manufactured by STMicroelectronics. It features two independent three-state buffers, each providing four-bit inverted output capability within a single 16-pin SOIC package. The device operates on a supply voltage range of 2V to 6V and supports an operating temperature from -55°C to 125°C. It delivers a maximum output current of 7.8mA for both high and low states. This component is part of the 74HC series and utilizes surface mount technology.

Feature Summary

• Provides dual independent three-state buffer functionality with inverted outputs
• Capable of driving six-bit wide buses through two separate control channels
• Features robust noise immunity and stable output characteristics typical of CMOS technology

Applications

• High-speed data bus buffering applications
• Clock distribution circuits requiring signal inversion
• Memory address and data line drivers in embedded systems

Procurement Notes

This specific part number is officially classified as obsolete and no longer manufactured by STMicroelectronics. Procurement must focus on verified direct or similar substitutes available from authorized distributors. Verify that replacement components match the original pinout and electrical specifications to ensure compatibility with existing designs.

Selection Notes

Designers should evaluate alternative manufacturers offering equivalent HC-series hex bus drivers. Key selection criteria include verifying the package type remains compatible with the PCB footprint and confirming that the substitute maintains the required three-state logic levels and voltage operating ranges for the target application environment.

Part Context

The M74HC368 belongs to the standard 74HC logic family, widely used for general-purpose digital logic functions. As a hex bus driver, it facilitates efficient data transfer across multiple lines while allowing tri-state control to prevent bus contention. The RM13 suffix indicates the specific tape and reel packaging format intended for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes include SN74HC368DR from Texas Instruments. Similar alternatives are available from Nexperia (74HC368D,653) and Texas Instruments (CD74HC368M). These parts maintain functional compatibility with the original design requirements.
