74HC4053D/AUJ

Overview

The NXP USA Inc. 74HC4053D/AUJ is a high-speed silicon-gate CMOS triple 2-channel analog multiplexer/demultiplexer. It features three independent switches, each with two inputs/outputs (nY0, nY1) and one common input/output (nZ), controlled by three digital select lines (S0-S2). A common enable input (E) controls the state of all switches simultaneously. The device operates within a supply voltage range of 2.0 V to 10.0 V for logic control. Analog signals can swing between VCC and VEE limits, supporting a wide analog input voltage range from -5 V to +5 V. It includes built-in ESD protection exceeding specified JEDEC standards.

Feature Summary

• Triple 2-channel analog switching architecture with common enable control
• Wide analog signal handling capability allowing communication between 5V logic and ±5V analog domains
• Integrated electrostatic discharge protection compliant with JESD22 standards

Applications

• Analog multiplexing and demultiplexing in data acquisition systems
• Signal routing in industrial process control equipment
• Audio signal switching in consumer electronics

Procurement Notes

Verify the specific suffix 'AUJ' against official NXP documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the exact mechanical dimensions required for the PCB footprint. Confirm RoHS compliance status through the manufacturer's current product change notification records.

Selection Notes

Select this component when a triple SPDT analog switch is required with low on-resistance characteristics. Verify that the operating temperature range meets the application environment requirements. Ensure the analog signal voltage does not exceed the supply rails plus diode drop limits to prevent internal clamp diode conduction issues.

Part Context

This device belongs to the 74HC series of high-speed CMOS logic components. It is pin-compatible with older HEF4053B devices but offers improved switching speeds and lower power consumption. The 74HC family is widely used in general-purpose digital and analog switching applications requiring standard CMOS logic levels.

Replacement Considerations

Direct replacements include the 74HCT4053 for TTL-compatible logic levels or other manufacturers' equivalents such as SN74HC4053. Verify pinout compatibility and electrical parameters before substitution.

FAQ

What is the function of the Enable (E) input?

When the Enable input is HIGH, all three analog switches are forced into a high-impedance OFF-state, regardless of the state of the select inputs S0 to S2.

How does the device handle analog voltages outside the supply range?

The analog inputs/outputs include clamp diodes. If the analog voltage exceeds VCC or goes below VEE, the diodes conduct, potentially requiring external current-limiting resistors to protect the device.

What is the typical on-resistance value?

The typical on-resistance varies with the voltage difference between VCC and VEE: approximately 80 Ω at 4.5 V, 70 Ω at 6.0 V, and 60 Ω at 9.0 V.
