FSAV330MTC Video Switch IC Equivalent & Substitute Parts

Part Overview

The FSAV330MTC is a quad 2:1 video switch interface IC manufactured by onsemi in 16-TSSOP surface mount packaging. This component functions as a 4-channel multiplexer/demultiplexer with SPDT switching architecture, designed for video signal routing applications. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain functional compatibility across switching characteristics, electrical performance, and physical form factor requirements.

Switch Circuit: SPDT topology
Number of Channels: 4 channels
Operating Temperature Range: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount
Package Form Factor: 16-pin TSSOP or equivalent 16-pin packages (TSSOP, TVSOP, SSOP)

Secondary Performance Criteria:

On-State Resistance: Maximum 10 Ohm (lower values acceptable)
Voltage Supply Range: Minimum 4V ~ 5.5V (3V ~ 3.6V parts require design verification)
-3dB Bandwidth: Minimum 300 MHz (higher values acceptable)

Substitute parts are grouped into two categories:

Category A - Direct Equivalents (Identical Electrical & Package Specifications): Parts maintaining 4V ~ 5.5V supply voltage, 10 Ohm on-state resistance, 300 MHz bandwidth, and 16-TSSOP packaging.

Category B - Functional Alternatives (Modified Electrical Specifications): Parts with 3V ~ 3.6V supply voltage or enhanced performance (lower on-state resistance, higher bandwidth) in compatible 16-pin packages. These require design review for voltage compatibility.

Engineering Selection Recommendations

Primary Recommendation - Direct Equivalent:

FSAV330MTCX (Fairchild Semiconductor, Active status) is the direct functional equivalent. It maintains identical electrical specifications (4V ~ 5.5V supply, 10 Ohm on-state resistance, 300 MHz bandwidth) and 16-TSSOP packaging. This part provides the highest compatibility with existing FSAV330MTC designs without circuit modification.

Secondary Recommendations - Active Status with Voltage Compatibility:

TS5V330CPWR and TS5V330DBQR (Texas Instruments, Active status) maintain the 4V ~ 5.5V supply voltage range and 10 Ohm on-state resistance. TS5V330CPWR is available in 16-TSSOP packaging with MSL 1 rating. TS5V330DBQR is available in 16-SSOP packaging but carries MSL 2 rating and Last Time Buy status.

Alternative Options - Lower Supply Voltage (Design Review Required):

TS3V330PWR (Texas Instruments, Active status) and TS3V340PWR (Texas Instruments, Active status) operate at 3V ~ 3.6V supply voltage. These parts are suitable only for designs that can accommodate lower supply voltage operation. TS3V340PWR offers enhanced performance with 6 Ohm on-state resistance and 500 MHz bandwidth. Both parts are ROHS3 compliant with MSL 1 rating and 16-TSSOP packaging.

Compliance Considerations:

All Texas Instruments substitute parts carry ROHS3 compliance certification. The original FSAV330MTC and FSAV330MTCX do not list RoHS status. For applications requiring RoHS compliance, Texas Instruments parts (TS3V330PWR, TS3V340PWR, TS5V330CPWR) are preferred.

Frequently Asked Questions (FAQ)

Q: Can TS3V330PWR be used as a direct replacement for FSAV330MTC?

A: TS3V330PWR is functionally compatible in terms of switching architecture (4-channel 2:1 SPDT) and packaging (16-TSSOP). However, it operates at 3V ~ 3.6V supply voltage versus the FSAV330MTC's 4V ~ 5.5V range. Direct substitution requires design verification that the lower supply voltage is compatible with the application circuit.

Q: What is the difference between TS3V330PWR and TS3V340PWR?

A: Both are Texas Instruments quad video switch ICs in 16-TSSOP packaging with 3V ~ 3.6V supply voltage. TS3V340PWR offers superior performance: 6 Ohm on-state resistance (versus 10 Ohm) and 500 MHz bandwidth (versus 300 MHz). TS3V340PWR is suitable for applications requiring lower insertion loss and higher frequency response.

Q: Why do some substitute parts use 16-SSOP packaging instead of 16-TSSOP?

A: 16-SSOP (0.154" width) and 16-TSSOP (0.173" width) are both 16-pin surface mount packages with different body widths. Parts in 16-SSOP packaging (TS3V330DBQR, TS5V330DBQR) require PCB layout modification and cannot be used as direct pin-compatible replacements. Use 16-TSSOP variants for direct substitution.

Q: Is FSAV330MTCX still in production?

A: FSAV330MTCX is listed as Active status with 24,103 pieces in stock, indicating current availability. However, Fairchild Semiconductor was acquired by ON Semiconductor. Verify long-term availability through current distributors.

Q: What does MSL 1 versus MSL 2 mean for component handling?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control. MSL 2 requires moisture control and has a 1-year shelf life limit. Parts with MSL 1 rating (FSAV330MTC, FSAV330MTCX, TS3V330DGVR, TS3V330PW, TS3V330PWR, TS3V340PW, TS3V340PWR, TS5V330CPWR) are preferred for inventory management.

Q: Can TS5V330DBQR be used despite Last Time Buy status?

A: TS5V330DBQR is electrically compatible (4V ~ 5.5V supply, 10 Ohm on-state resistance, 300 MHz bandwidth) but carries Last Time Buy status, indicating limited future availability. Use only if current inventory meets long-term production requirements. Prefer TS5V330CPWR for new designs.
