74LVC540ADTR2G

Overview

The MC74LVC540ADTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the LVC logic family. It features eight non-inverting buffers with three-state outputs, housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 1.2V to 3.6V. Key electrical parameters include a propagation delay of 8ns at 3.3V and output drive currents of ±24mA for both high and low states. It supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent non-inverting buffer channels
• Three-state output capability allowing bus sharing and isolation
• Low voltage operation compatible with 1.2V to 3.6V power supplies
• High drive strength supporting ±24mA output current

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'DTR2G' confirms the TSSOP-20 package and reel packaging format. Ensure the component meets RoHS compliance standards as indicated by the manufacturer's designation. Cross-reference the datasheet revision date to confirm pinout compatibility with existing PCB layouts before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring low-voltage CMOS logic with high-speed performance. The LVC series offers improved switching speeds compared to standard LVC devices while maintaining low power consumption. Consider the three-state feature if the design requires multiple devices to share a common data bus without contention.

Part Context

This part belongs to onsemi's 74LVC logic family, which bridges the gap between low-voltage CMOS and TTL-compatible interfaces. The 74LVC540 variant specifically provides octal buffering, making it suitable for parallel data transmission applications where signal integrity and speed are critical constraints in modern electronic designs.

Replacement Considerations

Check for direct equivalents such as the SN74LVC540A or similar octal buffers from other manufacturers that match the 20-TSSOP footprint and 1.2V-3.6V operating range. Verify that substitute parts maintain identical pin configurations and electrical characteristics to ensure seamless integration.
