NLAST4053DR2

Overview

The NLAST4053DR2 is a triple 2:1 analog switch-multiplexer fabricated in sub-micron Silicon Gate CMOS technology. It operates with single supplies of 3V to 5V or dual supplies up to ±3V, supporting 6Vpp signals without coupling capacitors. Key electrical parameters include a maximum on-resistance (RON) of 26Ω at VCC=3V and 5.5V, with a channel-to-channel matching (ΔRON) of 10Ω. The device features a -3dB bandwidth of 180MHz, charge injection of 12pC, and off-channel leakage current of 100nA. Switching times (Ton/Toff) are guaranteed at 23ns for VCC=4.5V. It utilizes a 16-SOIC package.

Feature Summary

• Improved linearity and lower on-resistance compared to standard HC4053 devices due to sub-micron silicon gate CMOS process.
• TTL compatible address and inhibit pins with over-voltage tolerance, allowing drive up to +6V regardless of VCC.
• Pin-for-pin replacement capability for industry standard versions including MAX4053 and MAX4053A.
• Bidirectional signal passing capability where NO, NC, and COM pins are identical and interchangeable.

Applications

• Audio and video signal routing in consumer electronics
• Data acquisition systems requiring analog multiplexing
• Industrial control systems utilizing TTL logic interfaces

Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Check for RoHS compliance status, as original specifications may differ from current manufacturing runs. Confirm package integrity upon receipt, ensuring no physical damage to the SOIC-16 leads. Validate datasheet revisions against the specific lot code to ensure parameter consistency.

Selection Notes

Select this component when low on-resistance and high linearity are required for analog signal switching. Ensure supply voltage constraints align with the 3V to 5V single or ±3V dual supply requirements. Consider the 16-SOIC package dimensions for PCB layout compatibility. Verify that the 23ns switching speed meets system timing requirements for address selection.

Part Context

The NLAST4053 series represents an improved iteration of the MC14053 and MC74HC4053, designed by onsemi. It belongs to the NLAS40 family of analog switches. The DR2 suffix specifically denotes the SOIC-16 package variant supplied in tape and reel format for automated assembly processes.

Replacement Considerations

Publicly confirmed pin-compatible replacements include the MAX4053 and MAX4053A. Designers should verify electrical parameter differences, particularly on-resistance and bandwidth, when substituting these alternative part numbers into existing circuits.

FAQ

Can the NLAST4053 operate with a single supply voltage?

Yes, the device supports single supply operation between 3V and 5V by tying the VEE pin (pin 7) to ground.

What is the maximum voltage tolerance for the address and inhibit pins?

The address and inhibit pins are over-voltage tolerant and can be driven up to +6V regardless of the VCC supply voltage.

Is the NLAST4053 compatible with 1.8V logic?

When operating with a VCC of 3.0V to 3.3V, the device can interface with 1.8V logic without requiring additional translators.
