Overview
The MC74HC4052ADTR2 is a dual 4-to-1 analog multiplexer/demultiplexer manufactured by onsemi using silicon-gate CMOS technology. It operates with a digital supply voltage (VCC) of 2.0 V to 6.0 V and an analog supply range (VCC – VEE) of 2.0 V to 12.0 V. The device features a maximum ON resistance of 190 Ω at VCC = 4.5 V and 100 Ω at VCC = 6.0 V, with a channel-to-channel matching difference (ΔRon) of 10 Ω at VCC = 6.0 V. Propagation delays are guaranteed up to 350 ns at VCC = 2.0 V and 75 ns at VCC = 6.0 V. It includes diode protection on all inputs/outputs and is housed in a TSSOP-16 package.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching speeds and low power consumption.
- Provides independent control of two separate 4-position analog switches via shared channel-select inputs.
- Features improved Ron linearity over input voltage compared to metal-gate CMOS counterparts.
- Includes built-in diode protection on all inputs and outputs to guard against static discharge.
Applications
- Analog signal routing in data acquisition systems
- Audio signal switching and mixing applications
- Programmable gain amplifier front-ends
- Multiplexing sensor inputs for microcontroller interfaces
Procurement Notes
Verify the specific ordering suffix 'DTR2' corresponds to the TSSOP-16 tape and reel packaging configuration. Confirm that the component meets RoHS compliance standards as indicated by the manufacturer's documentation. Ensure the source provides valid traceability for the silicon-gate CMOS process used in this logic family.
Selection Notes
Select this component when dual independent 4:1 analog switching is required within a single package. It is suitable for applications requiring operation across wide analog voltage swings defined by the VCC and VEE supplies. Consider the propagation delay specifications relative to the system clock speed and ensure the ON resistance characteristics meet the signal integrity requirements of the application.
Part Context
This part belongs to the MC74HC405xA series of high-performance analog multiplexers. It shares pinout compatibility with older metal-gate devices like the MC14052B but offers superior electrical performance due to silicon-gate fabrication. The 'A' designation indicates updated specifications compared to earlier versions, while the 'MC74HC' prefix denotes the specific logic family and commercial temperature grade.
Replacement Considerations
Direct pin-compatible replacements include the MC74HC4052ADR2G (SOIC-16) and MC74HC4052ADT (TSSOP-16 rail). Verify that substitute parts maintain the same silicon-gate CMOS architecture to ensure comparable Ron linearity and leakage current characteristics.
