NLAS4053DT Equivalent & Substitute Parts

Part Overview

The NLAS4053DT is a 3-circuit SPDT analog switch IC manufactured by onsemi, housed in a 16-TSSOP surface mount package. This device functions as a 2:1 multiplexer/demultiplexer with an on-state resistance of 26Ohm and operates across supply voltages of 3V to 5V (single supply) or ±3V (dual supply). The NLAS4053DT is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Suitable alternatives must maintain the same package footprint, circuit topology, and core electrical characteristics while meeting current product availability and compliance standards.

Substitute Part Grouping Explanation

Substitution of the NLAS4053DT is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Package type: 16-TSSOP surface mount (0.173", 4.40mm Width)
Circuit topology: SPDT 2:1 multiplexer with 3 circuits
On-state resistance range: Must accommodate applications designed for 26Ohm maximum
Supply voltage compatibility: Single supply 3V ~ 5V or dual supply ±3V operation
Operating temperature range: -55°C ~ 125°C minimum
Leakage current: 100nA maximum

Substitution Logic: Substitute parts are grouped based on on-state resistance characteristics. Parts with higher on-state resistance (74HC4053PW,118 at 120Ohm, 74HCT4053PW,118 at 130Ohm, 74LV4053PW,118 at 105Ohm, and Texas Instruments CD74HC4053 variants at 130Ohm) are functionally compatible in applications where the NLAS4053DT's lower resistance is not a critical design constraint. All candidates maintain identical package geometry, circuit count, and temperature operating range. Supply voltage ranges vary among substitutes; selection depends on the specific voltage rails available in the target application.

Engineering Selection Recommendations

For Active Production (Recommended Primary Choices):

CD74HCT4053PWR (Texas Instruments) is the preferred substitute for applications operating at 4.5V to 5.5V single supply. This part is actively manufactured, RoHS3 compliant, and maintains the full -55°C to 125°C operating temperature range of the original NLAS4053DT. It provides 130Ohm on-state resistance with 5Ohm channel matching and 200MHz bandwidth.

74HC4053PW,118 (Nexperia USA Inc.) serves as an alternative for designs requiring wider supply voltage flexibility (2V to 10V single supply). This part is active, RoHS3 compliant, and offers 120Ohm on-state resistance with superior 6Ohm channel matching. Operating temperature range is -40°C to 125°C.

74LV4053PW,118 (Nexperia USA Inc.) is suitable for low-voltage applications (1V to 6V single supply) and provides the lowest on-state resistance among active substitutes at 105Ohm, with exceptional 2Ohm channel matching. This part is RoHS3 compliant and active.

For Legacy System Maintenance:

CD74HC4053PWT and CD74HCT4053PWT (Texas Instruments) are available as Last Time Buy options. These parts maintain full compatibility with the NLAS4053DT in terms of package, circuit topology, and temperature range but have limited future availability.

Supply Voltage Compatibility:

3V to 5V single supply designs: CD74HCT4053PWR or 74HC4053PW,118
4.5V to 5.5V single supply designs: CD74HCT4053PWR (optimal)
Dual supply ±3V designs: CD74HC4053PWR or CD74HCT4053PWR (both support ±1V to ±5V)
Low-voltage designs (below 3V): 74LV4053PW,118

Compliance Consideration: All recommended substitutes are RoHS3 compliant, addressing the non-compliance status of the obsolete NLAS4053DT. This is critical for new designs and regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace NLAS4053DT with 74HC4053PW,118 without circuit modifications?

A: Direct PCB replacement is possible due to identical 16-TSSOP package geometry. However, the on-state resistance increases from 26Ohm to 120Ohm. Verify that your circuit design tolerates this higher resistance. If the application involves analog signal switching with impedance-sensitive paths, circuit simulation or bench testing is necessary to confirm performance.

Q: What is the key difference between CD74HC4053PWR and CD74HCT4053PWR?

A: Both are Texas Instruments parts in identical packages. CD74HC4053PWR operates at 2V to 6V single supply, while CD74HCT4053PWR is optimized for 4.5V to 5.5V single supply with TTL-compatible input thresholds. Select based on your system's supply voltage. Both support ±1V to ±5V dual supply operation.

Q: Why does 74LV4053PW,118 show 2µA leakage current instead of 100nA?

A: The 74LV4053PW,118 is optimized for low-voltage operation (1V to 6V) and exhibits higher leakage current as a trade-off. This part is suitable for applications where supply voltage is constrained below 3V. For standard 3V to 5V designs, use 74HC4053PW,118 or CD74HC4053PWR to maintain 100nA leakage specifications.

Q: Is the NLAS4053DT still available for purchase?

A: The NLAS4053DT is classified as obsolete. While legacy inventory may exist, new production is not available. All recommended substitutes are either active or Last Time Buy status, ensuring supply chain continuity for new designs.

Q: Do all substitute parts support the same operating temperature range as NLAS4053DT?

A: No. The NLAS4053DT operates from -55°C to 125°C. CD74HC4053PWR and CD74HCT4053PWR maintain this full range. Nexperia parts (74HC4053PW,118, 74HCT4053PW,118, 74LV4053PW,118) operate from -40°C to 125°C. For applications requiring -55°C operation, select Texas Instruments CD74HC4053PWR or CD74HCT4053PWR.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in 16-TSSOP surface mount packages with identical footprints. Packaging formats vary by supplier: Cut Tape (CT) & Digi-Reel, Tape & Reel (TR), Tube, and Bulk. Select based on your procurement and assembly requirements. The package case dimensions remain constant at 0.173" × 4.40mm width across all parts.

Q: Can I use 74LV4053PW,118 in a design originally specified for NLAS4053DT?

A: Yes, if your design operates within 1V to 6V single supply range. The 74LV4053PW,118 provides superior channel matching (2Ohm vs. 10Ohm) and higher bandwidth (200MHz vs. 180MHz). However, verify that the 105Ohm on-state resistance is acceptable for your signal path impedance. The higher leakage current (2µA vs. 100nA) may affect precision analog applications.
