SN74LV4053AD

Overview

The SN74LV4053AD is a triple 2-channel analog multiplexer/demultiplexer manufactured by Texas Instruments in a 16-pin SOIC package. It operates on a single supply voltage ranging from 1.65V to 5.5V, supporting mixed-mode voltage operation across all ports. The device handles both digital and analog signals with amplitudes up to 5.5V peak in either direction. Key electrical specifications include an on-state resistance of 75 Ohms maximum at 4.5V, propagation delay times between 1.5ns and 18ns depending on load and temperature, and a frequency response up to 60MHz. It features extremely low input current, latch-up performance exceeding 250mA per JESD 17, and ESD protection ratings of ±2000V (HBM) and ±1000V (CDM).

Feature Summary

• Supports mixed-mode voltage operation allowing simultaneous handling of analog and digital signals.
• Provides individual switch controls for precise channel selection and signal routing.
• Features low crosstalk between switches and high on-off output-voltage ratio.
• Includes robust electrostatic discharge protection and high latch-up immunity.

Applications

• Telecommunications systems requiring signal gating and isolation.
• Infotainment systems utilizing signal multiplexing for audio or video data.
• Analog-to-digital and digital-to-analog conversion systems for sensor signal routing.
• Home appliances and programmable logic circuits needing efficient signal switching.

Procurement Notes

Verify the specific ordering suffix against the latest TI Package Option Addendum, as the standard 'AD' designation may be obsolete while variants like 'ADR' remain active. Confirm RoHS compliance and lead finish details directly with the manufacturer or authorized distributors. Ensure the selected package variant matches the required thermal and mechanical constraints for the target PCB layout.

Selection Notes

Select this component when designing circuits that require multiple analog or digital signals to share a common resource, such as an ADC input. Consider the operating voltage range and signal amplitude limits to ensure compatibility with the system rails. Evaluate the on-state resistance and bandwidth requirements against the specific signal frequencies to maintain signal integrity without excessive distortion or attenuation.

Part Context

This device belongs to the SNx4LV4053A family of triple 2-channel analog multiplexers. It shares functional similarities with other members of the LV series but differs in packaging options and specific status classifications. The 'AD' suffix specifically denotes the 16-pin SOIC package, which is distinct from TSSOP, VQFN, or SOT-23-THIN variants available within the same product line.

Replacement Considerations

FAQ

Can the SN74LV4053AD handle signals larger than the supply voltage?

Yes, the device supports mixed-mode voltage operation, allowing it to transmit signals with amplitudes up to 5.5V peak regardless of the specific VCC level within its 1.65V to 5.5V operating range.

What is the maximum on-state resistance specified for this device?

The maximum on-state resistance is 75 Ohms when the supply voltage is 4.5V. This value increases at lower voltages and higher temperatures, reaching up to 225 Ohms under extreme conditions.

How does the device protect against electrostatic discharge?

The SN74LV4053AD provides ESD protection that exceeds JESD 22 standards, offering ratings of ±2000V for the Human-Body Model and ±1000V for the Charged-Device Model across all pins.
