Overview
The MC74HC4051FL2-ON is an analog multiplexer/demultiplexer manufactured by onsemi, belonging to the HC4051 logic family. It features a single 8-to-1 channel configuration housed in a 16-SOIC package with a wide body (SOIC-Wide-16). The device operates on a digital supply voltage ranging from 2 V to 6 V and supports an analog power supply range of 2.0 V to 12.0 V. Key electrical parameters include a maximum on-resistance of 190 Ohms, a bandwidth of 95 MHz, and a propagation delay of 75 ns. It functions within a temperature range of -55°C to +125°C.
Feature Summary
- Utilizes high-performance silicon-gate CMOS technology for fast switching speeds and low noise operation.
- Controls analog voltages varying across the complete power supply range from VCC to VEE.
- Features improved resistance linearity over input voltage compared to metal-gate CMOS counterparts.
- Includes diode protection on all inputs and outputs to enhance device reliability.
Applications
- Data acquisition systems requiring signal routing.
- Audio and video signal switching applications.
- Process control instrumentation for analog signal selection.
Procurement Notes
Verify the specific suffix FL2 against official datasheets to confirm package dimensions and tape/reel specifications. Confirm RoHS compliance status through manufacturer documentation. Ensure the component matches the SOIC-Wide-16 footprint requirements for your PCB layout.
Selection Notes
Select this component when an 8-channel analog switch is required with a wide analog voltage range up to 12 V. The HC4051 series offers lower on-resistance than older metal-gate devices. Verify that the 75 ns propagation delay meets system timing constraints.
Part Context
This part belongs to the MC54/74HC4051/52/53 family of analog multiplexers. These devices are pin-compatible with the older MC14051B series but utilize advanced silicon-gate CMOS technology. The family provides enhanced performance characteristics including faster propagation delays and lower on-resistance values.
Replacement Considerations
Direct replacements include other manufacturers' versions of the SN74HC4051 or MC74HC4051. Verify pinout compatibility and ensure the substitute supports the required 12 V analog supply range and SOIC-Wide-16 package.
FAQ
What is the maximum analog voltage the MC74HC4051 can handle?
The device supports an analog power supply range (VCC – VEE) of 2.0 V to 12.0 V, allowing it to control analog signals within this full range.
How does the on-resistance linearity compare to previous technologies?
The silicon-gate CMOS technology provides improved on-resistance linearity over the input voltage range compared to traditional metal-gate CMOS analog switches.
Is the device compatible with LSTTL outputs?
Yes, the channel-select and enable inputs are compatible with standard CMOS outputs and can be made compatible with LSTTL outputs using pullup resistors.
