Overview
The MC74HC4052ADT is a dual analog multiplexer/demultiplexer manufactured by onsemi, utilizing silicon-gate CMOS technology. It features two independent SP4T switches with common outputs/inputs, controlled by digital select lines A and B. The device supports an analog power supply range (VCC – VEE) of 2.0 to 12.0 V and a digital control supply range (VCC – GND) of 2.0 to 6.0 V. Key electrical parameters include a maximum ON resistance of 120 Ω at VCC=4.5V and -4.5V, a channel-to-channel ON resistance matching of 12 Ω, and a maximum off-channel leakage current of 1.0 μA at VCC=6.0V and VEE=-6.0V. Propagation delays are guaranteed up to 350 ns at VCC=2.0V. The component is housed in a TSSOP-16 package.
Feature Summary
- Dual independent SP4T analog switching architecture
- Silicon-gate CMOS construction for low noise and fast propagation
- Analog signal control across the complete power supply range
- Diode protection on all inputs and outputs
Applications
- Signal routing in data acquisition systems
- Audio signal switching and mixing
- Instrumentation input selection
- Communication equipment signal path management
Procurement Notes
Verify the ordering suffix 'DT' corresponds to the TSSOP-16 package configuration as specified in the manufacturer's documentation. Confirm that the specific revision level matches the design requirements. Ensure compatibility with the intended operating temperature range of -55°C to +125°C. Check for RoHS compliance status if required by the assembly process. Validate pinout alignment with the schematic footprint before procurement.
Selection Notes
Select this component when dual independent 4-channel analog switching is required within a single package. It is suitable for applications needing bidirectional signal flow and operation over a wide analog voltage range. Consider the ON resistance linearity and leakage specifications for precision signal paths. Ensure the digital control interface levels match the system logic voltages, potentially requiring pull-up resistors for LSTTL compatibility.
Part Context
This part belongs to the MC74HC405xA family, which includes the HC4051A (8-channel) and HC4053A (triple 2-channel). These devices share similar pinouts and functionality with the older metal-gate MC14052AB series but offer improved linearity and lower ON resistance due to advanced silicon-gate CMOS technology. The family is designed for high-performance analog switching applications.
Replacement Considerations
MC74HC4052ADWR2G: SOIC-16 package variant with identical electrical characteristics. MC74HC4052AN: PDIP-16 through-hole package alternative. MC74HC4052ADR2: SOIC-16 tape and reel packaging option. Verify package dimensions and thermal characteristics when substituting.
