M74HCT7007RM13TR

Overview

The M74HCT7007RM13TR is a high-speed CMOS hex buffer manufactured by STMicroelectronics using silicon gate C2MOS technology. It features six non-inverting buffers with open-drain outputs, designed for direct interfacing between HSC2MOS systems and TTL or NMOS components. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -55°C to +125°C. Key electrical characteristics include a typical propagation delay of 14ns at VCC=4.5V, balanced propagation delays (tPLH ≈ tPHL), and symmetrical output impedance with minimum drive currents of 4mA for both high and low states.

Feature Summary

• Features six non-inverting buffers with open-drain outputs suitable for wired-OR applications
• Designed for direct interface compatibility with TTL and NMOS logic families
• Includes input protection circuits against static discharge and transient excess voltage

Applications

• Buffering signals in digital logic circuits requiring open-drain configurations
• Interfacing high-speed CMOS systems with TTL-compatible components
• Implementing wired-OR logic functions on data buses

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific ordering suffix RM13TR corresponds to the SOIC-14 tape and reel packaging format. Check current lifecycle status as this product may be classified as obsolete. Ensure compliance with RoHS directives relevant to your region before procurement.

Selection Notes

Select this component when open-drain buffering capabilities are required for signal integrity in mixed-voltage environments. Consider the 4.5V to 5.5V supply constraint and ensure the application does not require push-pull outputs. Evaluate the -55°C to +125°C temperature range against environmental conditions. Verify pin compatibility with existing 74HC7007 footprints if replacing legacy designs.

Part Context

This part belongs to the M74HCT7007 series of hex buffers produced by STMicroelectronics. It utilizes C2MOS technology for high speed and low power dissipation. The device is functionally compatible with the standard 74 Series 7007 but offers improved performance metrics typical of modern CMOS implementations. It serves as a bridge component in digital systems requiring level shifting or bus driving with open-drain characteristics.

Replacement Considerations

Direct substitutes include other manufacturers' 74HCT7007 variants in SOIC-14 packages. Verify that replacement parts maintain the open-drain output configuration and meet the 4.5V-5.5V operating voltage requirements. Ensure thermal and electrical specifications align with the original design constraints.
