Overview
The MC74LVXT4051M is an analog multiplexer/demultiplexer manufactured by onsemi, utilizing high-performance silicon-gate CMOS technology. It features a single-pole eight-throw (SP8T) configuration with three digital channel-select inputs and an active-high enable input. The device operates within a digital supply voltage range of 2.5 V to 6.0 V and supports analog signals across the complete power supply range from VCC to VEE. Key electrical specifications 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 break-before-make switching characteristics.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast propagation speeds and low ON resistance.
- Features over-voltage tolerant (OVT) control inputs compatible with standard TTL levels.
- Supports both single-supply operation (VEE = GND) and split supplies up to ±3.0 V.
- Incorporates break-before-make circuitry to prevent signal shorting during switching.
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching applications
- Level translation between 3.0 V logic and ±3.0 V analog signals
Procurement Notes
Verify the specific package suffix 'M' corresponds to the SOEIAJ-16 case 966 form factor when sourcing. Confirm RoHS compliance status via the 'G' suffix if lead-free packaging is required. Ensure the ordering information matches the exact tape-and-reel or rail quantities specified in the manufacturer's documentation.
Selection Notes
Select this component for designs requiring high-speed analog switching with low distortion. The LVXT series provides superior linearity compared to metal-gate counterparts. Verify that the application voltage does not exceed the 6.0 V limit for the digital section or the ±6.0 V limit for the negative supply.
Part Context
This part belongs to the MC74LVXT4051 family of analog switches. It shares pinout compatibility with HC4051A and metal-gate MC14051B devices but offers enhanced performance through silicon-gate CMOS technology. The M suffix specifically denotes the SOEIAJ-16 surface-mount package variant.

FAQ
What is the maximum analog voltage swing supported?
The analog inputs/outputs can swing between VCC as the positive limit and VEE as the negative limit, provided the difference between VCC and VEE does not exceed 6.0 V.
How does the device handle unused channels?
Unused analog inputs/outputs may be left floating. However, tying them to VCC or GND through a low-value resistor helps minimize crosstalk and feedthrough noise.
Is external protection recommended for voltage transients?
Yes, if voltage transients above VCC or below VEE are anticipated, external Germanium or Schottky diodes are recommended to absorb current surges during clipping.
