Overview
The MC74LVXT8051DR2 is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer manufactured by onsemi. It provides an 8-channel to 1-channel switching configuration within a 16-pin SOIC package. The device operates with a single power supply ranging from 2.0 V to 6.0 V, supporting analog signals across the full supply range. Key electrical parameters include a maximum propagation delay of 30 ns at 2.0 V and 15 ns at 5.5 V, an on-resistance (Ron) of up to 40 Ω at 3.0 V, and a bandwidth of 80 MHz. It features low off-leakage current and improved linearity compared to metal-gate counterparts.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching speeds and low on-resistance.
- Provides diode protection on all inputs and outputs for overvoltage tolerance.
- Features digital control inputs compatible with TTL-type thresholds.
- Supports logic-level translation between different voltage domains.
Applications
- Interfacing 5.0 V circuits to 3.0 V circuits
- Logic-level translation from 1.8V CMOS to 3.0V CMOS
- Analog signal routing in data acquisition systems
Procurement Notes
Verify the ordering suffix DR2 corresponds to the tape and reel packaging format specified in the manufacturer's documentation. Confirm that the component meets RoHS compliance requirements if applicable to the assembly process. Ensure the SOIC-16 package dimensions align with the printed circuit board footprint design constraints.
Selection Notes
Select this component when an 8-to-1 analog switch is required with a wide operating voltage range. Consider the propagation delay specifications relative to the system clock speed. Evaluate the on-resistance linearity requirements for the specific analog signal path. Verify thermal dissipation capabilities based on the expected load current and ambient temperature conditions.
Part Context
This part belongs to the LVXT series of analog switches from onsemi. It shares pinout compatibility with older HC4051A and MC14051B devices, facilitating direct upgrades in existing designs. The DR2 suffix specifically denotes the tape and reel packaging variant intended for automated surface-mount assembly processes.
Replacement Considerations
Direct pin-compatible replacements include the MC74LVXT8051D and MC74LVXT8051DG variants. These alternatives offer identical electrical characteristics but differ in packaging quantity or lead-free status. Verify package dimensions and marking codes before substitution.
