Overview
The MC74VHC4051MG is a single-pole, eight-position analog multiplexer/demultiplexer manufactured by onsemi using high-performance silicon-gate CMOS technology. It features fast propagation delays, low ON resistance, and low OFF leakage currents. The device controls analog voltages across the complete power supply range from VCC to VEE. Digital control inputs are compatible with standard CMOS outputs and LSTTL outputs when pullup resistors are used. The component operates within a digital supply voltage (VCC) of 2.0 V to 6.0 V and an analog supply difference (VCC - VEE) of 2.0 V to 12.0 V. It is housed in a SOIC-16 package.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching speeds and low noise operation.
- Provides improved linearity and lower ON resistance compared to metal-gate CMOS counterparts.
- Includes diode protection on all inputs and outputs to guard against static voltages.
- Supports analog signal control across the full power supply range from VCC to VEE.
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching
- Instrumentation and measurement equipment
Procurement Notes
Verify the specific ordering suffix to confirm the package type and tape/reel specifications. Ensure the part number matches the required pinout and electrical characteristics for your design. Check the manufacturer's website for the most current status, as some devices in this family may be discontinued or subject to manufacturing transfers. Confirm RoHS compliance and lead-free status if required by your assembly process.
Selection Notes
Select the MC74VHC4051MG when an 8-channel analog switch is needed with high-speed performance and low distortion. Consider the VHC series over HC series for faster propagation delays and lower ON resistance. Ensure the analog signal amplitude stays within the VCC to VEE range to avoid clipping. Verify that the control logic levels match your system's CMOS or LSTTL standards.
Part Context
The MC74VHC4051 is part of the VHC405x family, which includes the dual 4-position VHC4052 and triple 2-position VHC4053. These devices share identical pinouts with the older HC4051A and metal-gate MC14051B families, facilitating direct upgrades. The VHC series offers enhanced speed and linearity while maintaining compatibility with existing designs.

FAQ
What is the maximum analog voltage swing the MC74VHC4051 can handle?
The maximum analog voltage swing is determined by the supply voltages VCC and VEE. The positive peak should not exceed VCC, and the negative peak should not go below VEE. The total difference between VCC and VEE can range from 2.0 V to 12.0 V.
How does the MC74VHC4051 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 that might be picked up by the unused switch.
Is the MC74VHC4051 compatible with LSTTL logic levels?
Yes, the Channel-Select and Enable inputs are compatible with standard CMOS outputs. With pullup resistors, they are also compatible with LSTTL outputs.
