Overview
The MC74HC4051F is a single 8-channel analog multiplexer/demultiplexer manufactured by onsemi. It utilizes silicon-gate CMOS technology to provide fast propagation delays, low ON resistance, and low OFF leakage currents. The device controls analog voltages varying across the complete power supply range from VCC to VEE. Digital control inputs select one of eight channels for connection to a common output or input via an internal analog switch. When the Enable pin is HIGH, all switches are turned off. The component features diode protection on all inputs and outputs and is compatible with standard CMOS logic levels.
Feature Summary
- Utilizes silicon-gate CMOS technology for high-speed switching and low power consumption
- Provides bidirectional analog signal routing through digitally controlled switches
- Includes built-in diode protection on all inputs and outputs against static discharge
- Features improved ON resistance linearity compared to metal-gate CMOS counterparts
Applications
- Data acquisition systems requiring multi-channel signal selection
- Audio signal routing and mixing applications
- Programmable gain amplifier front-ends
- Test and measurement equipment signal paths
Procurement Notes
Verify the specific suffix 'F' against official manufacturer documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperature ranges and voltage supplies before procurement. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.
Selection Notes
Select this component when an 8-channel analog switch is required with low ON resistance and high bandwidth. Verify that the digital control voltage levels match the system logic family. Consider the HC4851A variant if injection current protection is necessary for the application environment.
Part Context
This part belongs to the MC74HC4051A series of analog multiplexers. It shares pinout compatibility with the older metal-gate MC14051AB series while offering improved performance characteristics such as lower ON resistance and faster switching speeds due to silicon-gate CMOS fabrication.
Replacement Considerations
MC74HC4051ADR2G: Active replacement in 16-SOIC package. MM74HC4051MX: Obsolete alternative in SOIC-Narrow-16. M74HC4051: Pin-compatible alternative from STMicroelectronics.
