Overview
The MC74HC4066AN is a quad analog switch manufactured by onsemi, utilizing silicon-gate CMOS technology. It features four independent bilateral switches with SPST configuration in a 14-pin DIP package. The device operates on a single supply voltage ranging from 2.0 V to 12.0 V. Key electrical parameters include a maximum ON resistance of 70 Ω at 9.0 V and 12.0 V supplies, with a maximum propagation delay of 10 ns at these voltages. The OFF-channel leakage current is limited to 0.1 µA at 12.0 V. The component supports an operating temperature range from -55°C to +125°C and includes diode protection on all inputs and outputs.
Feature Summary
- High linearity and lower ON resistance over input voltage compared to metal-gate CMOS analog switches
- Low crosstalk between switches and low noise performance
- Diode protection provided on all inputs and outputs
- Wide power-supply voltage range supporting full analog signal swing
Applications
- Multiplexer and demultiplexer circuits for signal routing
- Sample-and-hold amplifier configurations
- Analog signal switching and gating applications
Procurement Notes
Verify the specific suffix 'AN' corresponds to the 14-pin PDIP package when sourcing replacements. Confirm RoHS compliance status as older production runs may differ. Check for automotive qualified variants if the application requires AEC-Q100 certification. Ensure the supplier provides official datasheets matching the MC74HC4066A designation to guarantee parameter accuracy.
Selection Notes
Select this component for applications requiring high-speed analog switching within a wide voltage range. The HC series offers faster propagation speeds than standard 4000B series devices. Consider the DIP package for prototyping or through-hole designs. Evaluate the ON resistance linearity requirements against the specific supply voltage conditions to ensure signal integrity.
Part Context
This device belongs to the 74HC logic family, providing compatibility with standard CMOS outputs. It serves as a high-performance alternative to older metal-gate CMOS switches like the MC14016 and MC14066, offering improved linearity and speed. The pinout remains identical to these legacy components, facilitating direct upgrades in existing designs.

FAQ
How does the ON resistance vary with supply voltage?
The maximum ON resistance decreases as the supply voltage increases. At 2.0 V, it is up to 120 Ω, while at 9.0 V and 12.0 V, it is limited to 70 Ω.
What is the maximum analog input voltage range?
The analog input voltage can range from GND to VCC, allowing the switch to control signals across the full power-supply range.
Is the device suitable for LSTTL interface?
Yes, with pull-up resistors, the ON/OFF control inputs are compatible with LSTTL outputs.
