MC74LVX541DTR2

Overview

The MC74LVX541DTR2G is an octal bus buffer fabricated with advanced high-speed CMOS technology. It operates within a supply voltage range of 2.0 V to 3.6 V and features non-inverting outputs with dual active-low output enables (OE1, OE2). The device provides high noise immunity and balanced propagation delays, achieving typical speeds of 5.0 ns at 3.3 V. Inputs tolerate voltages up to 5.5 V, facilitating interface between 5.0 V and 3.0 V systems. It includes power-down protection on inputs and meets RoHS compliance standards.

Feature Summary

• Dual independent output enable pins control the high-impedance state for flexible bus management
• Inputs tolerate 5.5 V signals while operating from lower supply voltages for direct system interfacing
• Advanced CMOS construction ensures low power dissipation alongside high-speed operation

Applications

• Bus-oriented memory and logic applications
• Clock drivers and buffering
• High-noise-immunity bidirectional bus translation

Procurement Notes

Verify the specific ordering suffix 'G' indicates a lead-free package compliant with RoHS directives. Confirm the 'DT' suffix corresponds to the TSSOP-20 package type required for your PCB layout. Ensure the datasheet revision matches your design specifications, as electrical characteristics may vary between revisions.

Selection Notes

Select this component when an octal buffer is required for 2.0 V to 3.6 V logic families. It is suitable for designs needing 5.0 V tolerant inputs without external level shifting. Consider the TSSOP-20 package dimensions and thermal dissipation capabilities relative to your board space constraints.

Part Context

This part belongs to the MC74LVX541 family of octal bus buffers. It shares functional compatibility with standard logic families but utilizes low-voltage CMOS technology. The device is designed to replace older bipolar Schottky TTL equivalents while maintaining lower power consumption and higher integration density.

FAQ

How does the device handle unused inputs?

Unused inputs must be tied to an appropriate logic voltage level, either GND or VCC, to ensure proper operation.

What is the maximum input voltage tolerance?

The inputs can tolerate DC voltages up to 5.5 V, allowing them to interface directly with 5.0 V systems even when the device is powered by lower voltages.
