MC74LCX07DT

Overview

The MC74LCX07DT is a hex buffer and non-inverting gate manufactured by onsemi. It features six independent channels, each handling one bit of data. The device utilizes an open-drain output configuration, supporting supply voltages ranging from 2V to 5.5V. It is housed in a 14-TSSOP surface-mount package with a width of 4.40mm. The component operates within a temperature range of -40°C to 85°C. Maximum output current capability is specified at 24mA for both high and low states. This part belongs to the 74LCX logic series.

Feature Summary

• Provides six independent non-inverting buffer channels for signal conditioning
• Features open-drain outputs suitable for voltage level translation and bus driving
• Operates across a wide supply voltage range from 2V to 5.5V
• Designed for surface-mount assembly in compact 14-TSSOP packages

Applications

• Voltage level shifting between different logic families
• Driving external loads requiring open-drain configurations
• General-purpose buffering in digital communication interfaces
• Signal isolation in mixed-voltage circuit designs

Procurement Notes

Verify RoHS compliance status carefully as documentation indicates non-compliance for this specific obsolete part number. Confirm end-of-life status through official manufacturer channels before finalizing design-in decisions. Check for valid replacement components if long-term availability is required. Ensure packaging type matches production requirements.

Selection Notes

Select this component only when open-drain outputs are explicitly required for the application. Verify that the 2V to 5.5V operating range aligns with system power rails. Consider the 14-TSSOP footprint constraints during PCB layout. Evaluate alternative active parts if lead-free manufacturing processes are mandatory due to regulatory restrictions.

Part Context

This device is part of the 74LCX family, which offers low-voltage CMOS performance. The MC74LCX07 specifically provides non-inverting buffering with open-drain outputs. It serves as a legacy component within onsemi's logic portfolio, often replaced by newer generation devices in modern designs.

Replacement Considerations

Direct substitutes include MC74LCX07DR2G and MC74LCX07DTR2G. These alternatives offer similar functionality but may differ in packaging or RoHS compliance status. Verify pin compatibility and electrical specifications before substitution.
