Overview
The MM74HC4051WMX is an 8-channel analog multiplexer implemented in advanced silicon-gate CMOS technology. It features bidirectional switches with low on-resistance and low off-leakage, allowing control of up to ±6V peak analog signals using 0 to 6V digital logic. The device includes linearization circuitry for improved switch linearity and an inhibit control input that disables all switches when HIGH. All analog inputs/outputs and digital inputs are protected against electrostatic discharge via diodes to VCC and ground. It operates within a supply voltage range of 2V to 6V and supports single or dual power supplies.
Feature Summary
- Bidirectional analog switching capability with integrated linearization circuitry
- Logic level translation enabling 5V logic control for ±5V analog signals
- Inhibit control input to disable all switches simultaneously
- ESD protection diodes on all analog and digital pins
Applications
- Data acquisition systems requiring signal routing
- Audio signal processing and switching applications
- Industrial process control instrumentation
- Test and measurement equipment signal paths
Procurement Notes
Verify the suffix 'X' indicates tape and reel packaging as specified in the datasheet ordering code section. Confirm the manufacturer origin, as this part was originally produced by Fairchild Semiconductor before its semiconductor business became onsemi. Ensure the wide SOIC-16 package (M16B) matches the design requirements.
Selection Notes
Select this component for applications requiring high channel count analog switching with low distortion. Verify the supply voltage configuration meets the ±6V analog input requirement. Consider the propagation delay and on-resistance variations across temperature ranges if precise timing or signal integrity is critical for the specific application environment.
Part Context
This device belongs to the MM74HC405x family, which also includes the MM74HC4052 (dual 4-channel) and MM74HC4053 (triple 2-channel). These devices share similar CMOS technology and pinout compatibility, facilitating multi-channel system designs. The MM74HC4051 specifically provides a single 8:1 multiplexing function.
Replacement Considerations
Direct pin-compatible replacements include other manufacturers' 74HC4051 variants in SOIC-16 packages. Verify electrical characteristics such as on-resistance and leakage current match the original specifications. Check for any differences in ESD protection levels or operating temperature ranges.
