Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICL7667CBA are grouped based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — mechanical and electrical interface compatibility
• Number of Drivers: 2 — functional channel count requirement
• Input Type: Inverting — logic signal inversion characteristic
• Gate Type: N-Channel MOSFET — output stage configuration
• Channel Type: Independent — dual independent driver channels
• Voltage - Supply: Minimum 4.5V, maximum ≥15V — power supply compatibility
• Logic Voltage - VIL, VIH: 0.8V threshold minimum, 2V threshold minimum — input signal compatibility

Direct Equivalent: ICL7667CBAZA matches all primary parameters identically and represents the active production equivalent from the same manufacturer.

Similar Substitutes: ICL7667CBA+, ICL7667EBA+, MIC4426YM, MIC4426YM-TR, and TC426COA provide functional substitution with variations in supply voltage range, operating temperature, and driven configuration. These parts maintain the core 8-SOIC package, dual independent channels, inverting input logic, and N-Channel MOSFET gate driving capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: ICL7667CBAZA

ICL7667CBAZA is the direct equivalent substitute for ICL7667CBA. This part maintains identical electrical specifications, package configuration, and functional characteristics while offering active product status and ROHS3 compliance. Selection of ICL7667CBAZA eliminates obsolescence risk and aligns with current regulatory requirements.

Secondary Recommendations: ICL7667CBA+ and ICL7667EBA+

Both ICL7667CBA+ and ICL7667EBA+ provide functional substitution with extended supply voltage range (4.5V ~ 17V) and expanded operating temperature range (0°C ~ 150°C TJ). These parts are manufactured by Analog Devices Inc./Maxim Integrated and carry ROHS3 compliance. Selection is appropriate for applications requiring enhanced thermal performance or higher supply voltage tolerance.

Alternative Recommendations: MIC4426YM, MIC4426YM-TR, TC426COA

MIC4426YM and MIC4426YM-TR (Microchip Technology) offer the widest supply voltage range (4.5V ~ 18V) and extended operating temperature range (-40°C ~ 150°C TJ). These parts support both N-Channel and P-Channel MOSFET gate driving with specified peak output current (1.5A source, 1.5A sink). MIC4426YM-TR is supplied in tape and reel packaging. TC426COA provides similar functionality with operating temperature range of 0°C ~ 70°C (TA) and specified peak output current characteristics.

All substitute parts maintain 8-SOIC package compatibility, dual independent channels, inverting input logic, and ROHS3 compliance status.

Frequently Asked Questions (FAQ)

Q: Can ICL7667CBAZA directly replace ICL7667CBA without circuit modification?

A: Yes. ICL7667CBAZA is the direct equivalent with identical electrical specifications, package configuration, and functional characteristics. No circuit modification is required.

Q: What is the primary difference between ICL7667CBA and MIC4426YM?

A: The primary differences are: (1) MIC4426YM supports both N-Channel and P-Channel MOSFET gate driving, while ICL7667CBA supports N-Channel only; (2) MIC4426YM specifies peak output current (1.5A source, 1.5A sink), while ICL7667CBA does not specify this parameter; (3) MIC4426YM operates across -40°C ~ 150°C (TJ), while ICL7667CBA operates 0°C ~ 70°C (TA); (4) MIC4426YM fall time is 29ns versus 20ns for ICL7667CBA.

Q: Are all substitute parts RoHS compliant?

A: ICL7667CBA is RoHS non-compliant. All listed substitute parts (ICL7667CBAZA, ICL7667CBA+, ICL7667EBA+, MIC4426YM, MIC4426YM-TR, TC426COA) are ROHS3 compliant.

Q: What packaging options are available for substitute parts?

A: ICL7667CBAZA, ICL7667CBA+, ICL7667EBA+, MIC4426YM, and TC426COA are supplied in tube packaging. MIC4426YM-TR is supplied in cut tape and Digi-Reel tape and reel packaging.

Q: Can MIC4426YM be used in applications originally designed for ICL7667CBA?

A: MIC4426YM provides functional substitution with compatible 8-SOIC package, dual independent channels, and inverting input logic. However, verify that the application does not require the specific N-Channel-only gate driving configuration or the exact 20ns rise/fall time specification of the original design. MIC4426YM's 29ns fall time and dual N/P-Channel capability represent functional variations.

Q: What is the inventory status of substitute parts?

A: ICL7667CBAZA: 2300 pcs. ICL7667CBA+: 1480 pcs. ICL7667EBA+: 916 pcs. MIC4426YM: 18008 pcs. MIC4426YM-TR: 2180 pcs. TC426COA: 1418 pcs.
