Overview
The MC74HC4066ADTR2G is a quad bilateral analog switch manufactured by onsemi using silicon-gate CMOS technology. It operates within a supply voltage range of 2.0 V to 12.0 V and supports analog signals across the full power-supply range. The device features four independent switches with low ON resistance, high OFF-channel leakage isolation, and fast propagation speeds. It is housed in a TSSOP-14 package (CASE 948G) and is designed for applications requiring improved linearity and lower ON resistance compared to metal-gate CMOS alternatives.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching and low ON resistance
- Provides four independent bilateral switches compatible with analog and digital voltages
- Includes diode protection on all inputs and outputs
- Offers low crosstalk between switches and high ON/OFF output voltage ratio
Applications
- Multiplexer and demultiplexer circuits
- Sample-and-hold amplifiers
- Gate arrays for signal routing
- ADC input multiplexing
Procurement Notes
Verify the specific ordering suffix 'DT' confirms the TSSOP-14 package configuration. Confirm RoHS compliance and Pb-Free status as indicated by the 'G' suffix or marking. Ensure the application environment stays within the recommended operating temperature range of -55°C to +125°C. Check for any automotive-specific requirements if the '-Q' suffix variant is needed.
Selection Notes
Select this component when a quad analog switch with wide supply voltage compatibility (2V to 12V) is required. Consider the TSSOP-14 package for surface-mount assembly needs. Evaluate the ON resistance linearity requirements against the provided graphs for specific supply voltages. Ensure control logic levels are compatible with standard CMOS outputs or use pull-up resistors for LSTTL compatibility.
Part Context
This part belongs to the MC74HC4066A series of high-performance silicon-gate CMOS analog switches. It is pin-compatible with older metal-gate CMOS devices like the MC14016 and MC14066 but offers improved performance characteristics including better linearity and lower ON resistance over the input voltage range.
Replacement Considerations
Direct pin-compatible replacements include the MC14016 and MC14066, though these are metal-gate technologies with different electrical characteristics. For automotive applications requiring unique site control, consider the MC74HC4066ADTR2G-Q variant which is AEC-Q100 qualified.
