PI3B16232A Equivalent & Substitute Parts

Part Overview

The PI3B16232A is a 16 x 1:2 Multiplexer/Demultiplexer logic IC manufactured by Diodes Incorporated in a 56-TSSOP surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part operates on a single supply voltage of 3V to 3.6V with an operating temperature range of -40°C to 85°C. Due to its obsolete status, equivalent substitutes from active product lines are necessary for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI3B16232A are identified based on the following critical parameters that determine functional equivalence:

• Circuit configuration and type (Multiplexer/Demultiplexer 16 x 1:2)
• Independent circuit count (1)
• Package compatibility (56-TFSOP / 56-TSSOP)
• Operating temperature range (-40°C ~ 85°C)
• Mounting type (Surface Mount)
• Single supply voltage operation

Two substitute parts meet these criteria with varying voltage supply specifications. The SN74CBT16232DGGR maintains identical circuit configuration and voltage supply characteristics. The SN74ALVCH16260DGGR provides functional substitution with different circuit topology (12:24 D-Type Addressable) and expanded voltage supply range, suitable for applications requiring broader voltage compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74CBT16232DGGR from Texas Instruments is the primary substitute for the PI3B16232A. This part maintains identical circuit configuration (16 x 1:2 Multiplexer/Demultiplexer), package form factor (56-TFSOP), and operating temperature range. The primary design consideration is the voltage supply specification: the SN74CBT16232DGGR operates at 4.5V to 5.5V, requiring voltage adjustment from the original 3V to 3.6V specification. This part carries Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The SN74ALVCH16260DGGR provides an alternative substitute with expanded voltage supply compatibility (1.65V to 3.6V), which encompasses the original 3V to 3.6V range. However, this part implements a different circuit topology (12:24 D-Type Addressable) rather than the original 16 x 1:2 Multiplexer/Demultiplexer configuration. Selection of this part requires functional verification that the D-Type Addressable logic topology meets application requirements. This part also carries Active product status and ROHS3 compliance.

Both substitutes are available in the same 56-TFSOP package and maintain the -40°C to 85°C operating temperature range, ensuring mechanical and thermal compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the SN74CBT16232DGGR directly replace the PI3B16232A without circuit modifications?

A: The SN74CBT16232DGGR maintains identical circuit configuration and package form factor. The primary design consideration is voltage supply: the substitute operates at 4.5V to 5.5V versus the original 3V to 3.6V. Circuit modifications to accommodate this voltage difference are required.

Q: What is the functional difference between the SN74CBT16232DGGR and SN74ALVCH16260DGGR?

A: The SN74CBT16232DGGR implements a 16 x 1:2 Multiplexer/Demultiplexer configuration identical to the original part. The SN74ALVCH16260DGGR implements a 12:24 D-Type Addressable logic topology with tri-state output. These represent different functional architectures and require application-specific evaluation.

Q: Are both substitute parts available in the same package as the PI3B16232A?

A: Yes. Both the SN74CBT16232DGGR and SN74ALVCH16260DGGR are available in the 56-TFSOP (0.240", 6.10mm Width) package, matching the original PI3B16232A package specification.

Q: What is the inventory status of these substitute parts?

A: The SN74CBT16232DGGR has 2000 pieces in stock. The SN74ALVCH16260DGGR has 4993 pieces in stock. Both are available as new original components in tape and reel packaging.

Q: Do the substitute parts meet current RoHS compliance requirements?

A: Yes. Both the SN74CBT16232DGGR and SN74ALVCH16260DGGR carry ROHS3 compliance status, whereas the original PI3B16232A is RoHS non-compliant. This represents an improvement in regulatory alignment for new designs.

Q: What is the moisture sensitivity level of the substitute parts?

A: Both substitute parts maintain MSL 1 (Unlimited) moisture sensitivity level, identical to the original PI3B16232A specification.
