FSAV330M Equivalent & Substitute Parts

Part Overview

The FSAV330M is a quad 2:1 video switch IC manufactured by onsemi in a 16-SOIC package. This interface component operates as a multiplexer/demultiplexer with SPDT switching architecture across four channels, designed for video signal routing applications. The part is currently obsolete, making equivalent substitute parts necessary for new designs or production continuity. Substitute parts must maintain electrical compatibility across supply voltage, on-state resistance, bandwidth, and channel configuration while accommodating available packaging options.

Number of Channels: 4
Operating Temperature: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount
On-State Resistance (Max): ≤ 10 Ohm
-3dB Bandwidth: ≥ 300 MHz

Acceptable Variations:

Voltage Supply Range: Parts rated for 3V ~ 3.6V or 4V ~ 5.5V are acceptable if the application operates within the overlapping range or if the design accommodates the lower voltage specification
Package / Case: 16-SOIC and 16-TSSOP are both 16-pin surface mount packages with compatible pinouts for this device class
Application: Video-specific parts are primary substitutes; networking switch parts (TS3L110 series) are secondary options if electrical parameters align

Substitute parts are grouped into two categories: direct video switch equivalents and alternative interface switches meeting core electrical requirements.

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

FSAV330MTCX is the closest functional equivalent, maintaining identical electrical specifications (10 Ohm on-state resistance, 300 MHz bandwidth, 4V ~ 5.5V supply) with active product status. The only difference is packaging format (16-TSSOP vs. 16-SOIC), which requires PCB layout modification but offers superior availability (24,103 units in stock).

TS5V330DR and TS5V330D maintain the original 4V ~ 5.5V supply voltage and 300 MHz bandwidth with 10 Ohm on-state resistance. TS5V330DR is in active production with highest inventory (16,085 units), while TS5V330D is Last Time Buy status. Both use 16-SOIC packaging compatible with the original footprint.

Secondary Substitutes (Voltage-Dependent):

TS3V330DR and TS3V330D are suitable for applications operating at 3V ~ 3.6V supply voltage. These maintain 10 Ohm on-state resistance and 300 MHz bandwidth in 16-SOIC packaging with active product status. TS3V330DR offers higher inventory (4,459 units).

Performance-Enhanced Alternatives:

TS3V340DR and TS3V340D provide improved performance specifications (6 Ohm on-state resistance, 500 MHz bandwidth) for 3V ~ 3.6V applications. These are suitable if the design can accommodate lower supply voltage and benefits from reduced insertion loss and higher bandwidth.

Secondary Application Compatibility:

TS3L110DR and TS3L110D are networking switch ICs with 8 Ohm on-state resistance and 500 MHz bandwidth at 3V ~ 3.6V supply. These meet core switching requirements but are specified for networking applications. Selection requires confirmation that video signal characteristics are compatible with networking-grade switching performance.

Compliance and Availability:

All recommended substitutes carry RoHS3 compliance and REACH Unaffected status where specified. TS5V330DR provides the highest inventory availability (16,085 units) among direct voltage-matched equivalents. FSAV330MTCX offers maximum stock (24,103 units) with identical electrical performance but requires package footprint change.

Frequently Asked Questions (FAQ)

Q: Can TS3V330DR replace FSAV330M directly?

A: TS3V330DR is electrically compatible if your application operates at 3V ~ 3.6V supply voltage. It maintains identical on-state resistance (10 Ohm), bandwidth (300 MHz), channel count (4), and uses the same 16-SOIC package. If your design requires 4V ~ 5.5V operation, use TS5V330DR instead.

Q: What is the difference between TS5V330D and TS5V330DR?

A: Both parts are identical in electrical specifications and packaging (16-SOIC, 4V ~ 5.5V, 10 Ohm, 300 MHz). The difference is packaging format: TS5V330D is supplied in Tube, while TS5V330DR is supplied in Tape & Reel (TR). TS5V330DR has significantly higher inventory (16,085 vs. 1,726 units). Both are Last Time Buy status.

Q: Why is FSAV330MTCX in 16-TSSOP instead of 16-SOIC?

A: FSAV330MTCX is the Fairchild Semiconductor equivalent with identical electrical performance but different package format. 16-TSSOP (Thin Shrink Small Outline Package) is a narrower package (0.173" vs. 0.154" width) than 16-SOIC. This requires PCB layout modification but offers superior availability and active product status.

Q: Can I use TS3L110DR for video applications?

A: TS3L110DR is specified for networking applications but meets core switching requirements: 4 channels, SPDT configuration, 8 Ohm on-state resistance (better than 10 Ohm), and 500 MHz bandwidth (exceeds 300 MHz requirement). Compatibility depends on whether your video signal characteristics are compatible with networking-grade switching performance. Electrical parameters are acceptable; application suitability requires design verification.

Q: What is the difference between TS3V340D and TS3V330D?

A: TS3V340D provides enhanced performance: 6 Ohm on-state resistance (vs. 10 Ohm) and 500 MHz bandwidth (vs. 300 MHz). Both operate at 3V ~ 3.6V and use 16-SOIC packaging. TS3V340D is suitable if your design can accommodate lower supply voltage and benefits from reduced insertion loss and higher bandwidth capability.

Q: Is FSAV330MTCX still in production?

A: Yes, FSAV330MTCX is Active product status with 24,103 units in stock. The original FSAV330M is Obsolete. FSAV330MTCX is the recommended substitute for new designs requiring the Fairchild equivalent.

Q: What does "Last Time Buy" mean for TS5V330D and TS5V330DR?

A: Last Time Buy status indicates these parts are being discontinued. Existing inventory is available, but no future production is planned. For long-term supply security, prioritize TS5V330CDR (Active status) or FSAV330MTCX (Active status) for new designs.
