MC74LVXT4052DG

Overview

The MC74LVXT4052DG is a dual 4-to-1 analog multiplexer/demultiplexer manufactured by onsemi, utilizing advanced silicon gate CMOS technology. It operates within a supply voltage range of 2.5 V to 6 V and supports both single and dual supply configurations. The device features two independent channels, each configured as a 4:1 switch, providing eight total selectable paths. Key electrical specifications include a maximum propagation delay of 23 ns, an 80 MHz bandwidth, and a maximum on-resistance of 86 Ohms. It is housed in a 16-pin SOIC package with a wide operating temperature range from -55°C to +125°C.

Feature Summary

• Dual-channel architecture enabling simultaneous control of two independent 4:1 analog signal paths
• Low on-resistance characteristic ensuring minimal signal attenuation across the conduction path
• High-speed switching capability with nanosecond-level propagation delays for efficient data routing
• Wide operational voltage compatibility supporting low-power system designs

Applications

• Analog signal routing in portable battery-powered equipment
• Data acquisition systems requiring multi-channel input selection
• Audio signal switching applications in consumer electronics
• Industrial process control systems managing multiple sensor inputs

Procurement Notes

Verify the specific suffix 'DG' against the manufacturer's current product status documentation, as availability may vary between active production and obsolescence phases. Confirm that the SOIC-16 package outline matches the mechanical constraints of the target PCB layout. Ensure compliance requirements such as RoHS directives are explicitly documented in the official datasheet before finalizing component selection for mass production.

Selection Notes

Select this component when a dual 4:1 analog switching configuration is required within a 2.5 V to 6 V supply environment. The LVXT series offers faster switching speeds compared to standard LVX counterparts, making it suitable for higher frequency applications. Consider the 86 Ohm on-resistance limit when designing for precision analog signals where voltage drop across the switch must be minimized. Verify thermal dissipation capabilities if operating at the upper limits of the specified temperature range.

Part Context

This part belongs to the MC74LVXT4052 family of high-performance silicon gate CMOS analog switches. It is functionally compatible with legacy metal oxide semiconductor devices like the MC14052B but offers improved speed and lower power consumption. The device serves as a direct replacement for older generation multiplexers in modern low-voltage digital and mixed-signal circuits, maintaining pin-out compatibility while enhancing performance metrics.

Replacement Considerations

The MC74LVXT4052DR2G is a verified alternative offering identical electrical characteristics in a reel packaging format. Designers should verify that the SOIC-16 footprint remains consistent across these variants to ensure mechanical interchangeability without PCB redesign.
