MC74VHC4053DR2

Overview

The MC74VHC4053DR2 is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer manufactured by onsemi. It integrates three independent single-pole double-throw (SPDT) switches within a 16-pin SOIC package. The device supports an analog power supply range of 2.0 V to 12.0 V and a digital control supply range of 2.0 V to 6.0 V. Key electrical characteristics include a maximum ON resistance of 100 Ω at 6.0 V, a maximum OFF leakage current of 1.0 μA, and a -3 dB bandwidth of 120 MHz. Propagation delays are specified at 45 ns for channel select-to-output transitions at 6.0 V.

Feature Summary

• Utilizes silicon-gate CMOS technology to achieve fast switching speeds and low noise performance.
• Features diode protection on all inputs and outputs to guard against voltage transients.
• Provides improved linearity and lower ON resistance compared to metal-gate CMOS counterparts.
• Channel-select and enable inputs are compatible with standard CMOS and LSTTL logic levels.

Applications

• Signal routing in data acquisition systems
• Audio signal switching and matrix routing
• Test and measurement equipment signal paths

Procurement Notes

Verify the specific ordering suffix DR2 corresponds to the SOIC-16 tape and reel configuration as defined in the manufacturer's documentation. Confirm that the component meets RoHS compliance standards required for the target assembly process. Ensure the supply voltage constraints are strictly observed during operation to prevent device damage.

Selection Notes

Select this component when three independent SPDT analog switching functions are required in a compact surface-mount package. It is suitable for applications requiring bidirectional signal flow controlled by digital logic levels. Consider the 100 Ω ON resistance and 120 MHz bandwidth limits when designing for high-frequency or precision analog signal integrity.

Part Context

This device belongs to the MC74VHC405x family of analog multiplexers, which also includes the 8-channel VHC4051 and the dual 4-channel VHC4052. These devices share identical pinouts with the legacy HC4051A/HC4052A/HC4053A series and the metal-gate MC14051B/MC14052B/MC14053B series, facilitating direct pin-compatible upgrades.

Replacement Considerations

Public confirmed substitute part numbers include MC74VHC4053DTR2G.

FAQ

How does the MC74VHC4053 handle unused analog channels?

Unused analog inputs or outputs may be left floating. However, tying them to VCC or GND through a low-value resistor is recommended to minimize crosstalk and feedthrough noise.

What is the function of the Enable pin?

When the Enable pin is held HIGH, all internal analog switches are turned off, isolating the common output/input from the selected channels.

Can the device operate with unbalanced power supplies?

Yes, balanced supplies are not required. The constraints are that VCC-GND must be 2 to 6 volts, VEE-GND must be 0 to -6 volts, and VCC-VEE must be 2 to 12 volts.
