MC74LVXT4051DTR2G

Overview

The MC74LVXT4051DTR2G is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer manufactured by onsemi. It features an 8-channel configuration with a single common output/input, controlled by three channel-select inputs and an enable pin. The device operates on a digital supply voltage (VCC) ranging from 2.5 V to 6.0 V, while the analog power supply range (VCC − VEE) supports split supplies up to ±3.0 V or single-supply operation. Key electrical parameters include a maximum propagation delay of 40 ns at 2.5 V, a typical bandwidth of 80 MHz, and a maximum ON resistance of 86 Ω at 3.0 V. It offers low leakage currents, improved linearity, and overvoltage-tolerant control inputs.

Feature Summary

• Utilizes silicon-gate CMOS technology for fast switching speeds and low noise performance.
• Features break-before-make circuitry to prevent signal shorting during channel transitions.
• Control inputs are overvoltage tolerant, enabling level translation from 6.0 V down to 3.0 V.
• Provides improved ON resistance linearity compared to metal-gate or High-Speed CMOS counterparts.

Applications

• Analog signal routing in data acquisition systems
• Level translation between different logic voltage domains
• Audio and video signal switching applications

Procurement Notes

Verify the specific ordering suffix 'DTR2G' corresponds to the TSSOP-16 package and tape-and-reel shipping format. Confirm RoHS compliance and lead-free status as indicated by the 'G' suffix. Ensure the application environment stays within the recommended operating temperature range of -55°C to +125°C and respects the absolute maximum ratings for supply voltages and input currents.

Selection Notes

Select this component when a single-pole 8-position analog switch is required with LVX-level performance. It is suitable for designs needing compatibility with standard CMOS outputs and overvoltage tolerance on control lines. Consider the TSSOP-16 package constraints and ensure the analog signal swing remains within the VCC and VEE supply limits to avoid clipping or excessive leakage.

Part Context

This part belongs to the MC74LVX4051 family of analog multiplexers. It shares functional similarities with the HC405nA and metal-gate MC1405nB but offers superior speed and lower ON resistance. The 'T' suffix denotes the LVXT variant, which typically features optimized input structures for better compatibility with modern low-voltage logic families.

Replacement Considerations

MC74LVX4051DTR2G is a direct pin-compatible alternative within the same family. For non-automotive applications, MC74LVX4051DR2G (SOIC-16) may be considered if package changes are acceptable. Verify that any substitute maintains the required 80 MHz bandwidth and 40 ns propagation delay specifications.
