74LCX07MTC

Overview

The onsemi 74LCX07MTC is a hex buffer and line driver belonging to the LCX logic family, housed in a 14-pin TSSOP surface-mount package. It features six non-inverting channels with open-drain outputs capable of sinking up to 32 mA. The device operates within a supply voltage range of 2 V to 5.5 V, supporting 5 V tolerant inputs for seamless interfacing between 3.3 V and 5 V systems. Propagation delay is specified at 3.7 ns under a 50 pF load at 3.3 V, with a maximum operating temperature of +85 °C.

Feature Summary

• Provides six independent non-inverting buffer channels with open-drain output configuration
• Features 5 V tolerant inputs allowing direct interface between 3.3 V and 5 V logic systems
• Utilizes advanced CMOS technology to achieve low static current consumption
• Includes proprietary noise and EMI suppression circuitry for signal integrity

Applications

• Memory address and data bus buffering in embedded systems
• Clock distribution networks requiring high drive capability
• Interface bridging between 3.3 V microcontrollers and 5 V peripherals
• General-purpose logic level translation in industrial control equipment

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Confirm RoHS compliance status and environmental certifications prior to integration. Check for obsolescence notices or lifecycle changes as availability may vary by region. Ensure thermal management aligns with the specified -40 °C to +85 °C operating range for your application environment.

Selection Notes

Select this component when high-current sink capability is required for driving capacitive loads or multiple inputs. The open-drain architecture allows for wired-OR configurations and voltage level shifting beyond the supply rail. Compare propagation delays and output drive strengths against alternative LCX series parts to ensure timing margins are met for your specific clock frequencies.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices designed for high-speed applications. It serves as a buffer variant within the broader 74xx logic family, offering improved performance over older LS or HC technologies while maintaining compatibility with standard logic levels. The TSSOP-14 package provides a compact footprint suitable for dense PCB layouts.

Replacement Considerations

Cross-reference with MC74LCX07DR2G for SOIC-14 packaging alternatives from the same manufacturer. Verify pinout compatibility before substituting with other hex buffer ICs from different vendors.
