MC74VHC4052DTR2G

Overview

The MC74VHC4052DTR2G is a dual 4-to-1 analog multiplexer/demultiplexer manufactured by onsemi using silicon-gate CMOS technology. It features two independent SP4T switches with common channel-select logic (A and B) and an active-high enable input. The device supports a digital supply voltage range of 2.0 V to 6.0 V and an analog supply range of 2.0 V to 12.0 V. Key electrical parameters include a maximum ON resistance of 100 Ω at 6.0 V, a -3 dB bandwidth of 95 MHz, and a maximum OFF leakage current of 100 nA. It operates within a temperature range of -55°C to +125°C and is housed in a 16-TSSOP package.

Feature Summary

• Utilizes high-performance silicon-gate CMOS technology for fast switching speeds and low power consumption.
• Provides improved linearity and lower ON resistance compared to traditional metal-gate CMOS counterparts.
• Features diode protection on all inputs and outputs to guard against high static voltages.
• Compatible with standard CMOS outputs and LSTTL outputs when pull-up resistors are used.

Applications

• Signal routing in data acquisition systems
• Audio signal switching and mixing
• Test and measurement equipment multiplexing

Procurement Notes

Verify the specific ordering suffix 'DT' confirms the TSSOP-16 package type as documented in the official datasheet. Confirm RoHS compliance and Pb-free status through the manufacturer's material declaration. Ensure the component matches the exact part number MC74VHC4052DTR2G to guarantee pinout and electrical specifications align with design requirements.

Selection Notes

Select this component for applications requiring dual independent analog switching with wide supply voltage flexibility. The VHC series offers superior speed and linearity over HC series devices. Verify that the required analog signal swing remains within the VCC to VEE limits. Consider the 100 Ω ON resistance and 95 MHz bandwidth for signal integrity in high-frequency or precision applications.

Part Context

This device belongs to the MC74VHC405x family, which includes single-pole 8-position (MC74VHC4051) and triple single-pole double-throw (MC74VHC4053) variants. All members share identical pinouts and utilize the same silicon-gate CMOS process. The family is designed to be pin-compatible with older HC4052A and MC14052B devices while offering enhanced performance characteristics.

Replacement Considerations

Publicly confirmed direct substitutes include the NLVVHC4052DTR2G variant, which shares the same functional specifications but carries an automotive qualification prefix. Other family members like MC74VHC4051DTR2G offer different channel counts and are not direct replacements without schematic modification.

FAQ

What is the maximum analog voltage swing supported by the MC74VHC4052DTR2G?

The analog input/output voltage can swing across the complete power supply range from VEE to VCC, with a maximum difference of 12.0 V between VCC and VEE.

How does the Enable pin affect the switch state?

When the Enable pin is HIGH, all analog switches are turned off, placing the channels in a high-impedance state regardless of the Channel-Select inputs.

Is the MC74VHC4052DTR2G compatible with LSTTL logic levels?

Yes, the Channel-Select and Enable inputs are compatible with LSTTL outputs when external pull-up resistors are utilized.
