MC74LCX07DTG

Overview

The MC74LCX07DTG is a hex buffer and line driver from the onsemi LCX logic family, housed in a 14-pin TSSOP surface-mount package. It features six non-inverting channels with open-drain outputs capable of driving up to 24 mA at low levels. The device operates within a supply voltage range of 2 V to 5.5 V, ensuring compatibility with various logic standards. Key electrical characteristics include a propagation delay of approximately 3.7 ns at 5 V with a 50 pF load. It supports TTL input levels and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides six independent non-inverting buffer channels for signal conditioning
• Features open-drain outputs suitable for wired-OR configurations and level shifting
• Supports high drive current capability for interfacing with heavy loads
• Compatible with both 2.5 V and 5 V CMOS and TTL logic families

Applications

• Memory address and data bus buffering
• Clock distribution and timing signal conditioning
• Level translation between different voltage domains
• General-purpose digital signal buffering in embedded systems

Procurement Notes

Verify the specific suffix 'DTG' corresponds to the TSSOP-14 package and tape-and-reel or tube packaging as required by your assembly process. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain guaranteed electrical performance and reliability standards.

Selection Notes

Select this component when high-drive open-drain buffering is required for multiple signals in a compact surface-mount footprint. The wide supply voltage range allows flexibility in system design, supporting both low-power 2.5 V applications and standard 5 V interfaces. Consider the propagation delay specifications if signal integrity and timing margins are critical for your specific application frequency requirements.

Part Context

This part belongs to the 74LCX series, which utilizes advanced CMOS technology to achieve low power consumption while maintaining high-speed performance. The LCX family is designed to be pin-compatible with legacy 74HC and 74HCT devices, facilitating easier upgrades in existing designs. The MC74LCX07 specifically addresses the need for robust buffering with open-drain output capabilities, distinguishing it from standard push-pull buffer variants within the same logic family.

Replacement Considerations

Direct pin-compatible alternatives may include other manufacturers' 74LCX07 variants in TSSOP-14 packages. Verify that substitute parts meet the same 24 mA drive current and 2 V to 5.5 V operating voltage specifications. Cross-reference datasheets to ensure identical propagation delay and input threshold characteristics for seamless functional replacement.
