PI6C180VE Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The PI6C180VE is a Clock Fanout Buffer (Distribution) IC manufactured by Diodes Incorporated, designed for 1:18 clock distribution at frequencies up to 100 MHz. This component features TTL input/output compatibility and operates within a 3.135V to 3.465V supply voltage range in a 48-BSSOP surface mount package.

The PI6C180VE is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this legacy device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI6C180VE are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Ratio - Input:Output: 1:18 (exact match required)
• Frequency - Max: 100 MHz (minimum requirement)
• Voltage - Supply: 3.135V ~ 3.465V (exact match required)
• Operating Temperature: 0°C ~ 70°C (minimum requirement)
• Package / Case: 48-BSSOP (0.295", 7.50mm Width) (exact match required)

Logic Compatibility: The PI6C180VE specifies TTL input and TTL output. Substitute parts must support TTL output as a minimum. LVTTL (Low Voltage TTL) input compatibility is acceptable as LVTTL is a subset of TTL specifications and maintains backward compatibility with TTL output stages.

Compliance & Status: All substitute parts must maintain ROHS3 compliance and active product status to ensure long-term availability and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both CDC318ADL and CDC318ADLR are qualified substitutes for the PI6C180VE based on electrical parameter equivalence and package compatibility. Both parts are manufactured by Texas Instruments and maintain active product status, ensuring continued availability and supply chain stability.

CDC318ADL is supplied in Tube packaging and is suitable for applications where standard tube quantities are acceptable.

CDC318ADLR is supplied in Cut Tape (CT) & Digi-Reel® packaging and is suitable for high-volume production environments and automated assembly processes.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original PI6C180VE specification.

Frequently Asked Questions (FAQ)

Q: Can CDC318ADL or CDC318ADLR directly replace PI6C180VE in existing designs?

A: Yes. Both parts meet the critical electrical parameters: 1:18 distribution ratio, 100 MHz maximum frequency, 3.135V to 3.465V supply voltage, and 48-BSSOP package. The TTL output compatibility of both substitutes ensures signal integrity with existing TTL input stages in the system.

Q: What is the difference between CDC318ADL and CDC318ADLR?

A: The parts are electrically identical. CDC318ADL is packaged in Tube format, while CDC318ADLR is packaged in Cut Tape (CT) & Digi-Reel® format. Selection depends on procurement and assembly requirements. CDC318ADLR is preferred for automated high-volume production.

Q: Does the LVTTL input specification of the substitute parts affect compatibility?

A: No. LVTTL input is compatible with TTL output stages. The substitute parts accept LVTTL input signals and provide both LVTTL and TTL output options, maintaining full compatibility with the original PI6C180VE specification.

Q: Are there any moisture sensitivity considerations when substituting?

A: The PI6C180VE has MSL 1 (Unlimited), while both substitute parts have MSL 2 (1 Year). This means substitute parts require storage and handling within a 1-year moisture exposure window. Standard component storage practices will satisfy this requirement.

Q: Is the 48-BSSOP package identical across all three parts?

A: Yes. All three parts use the 48-BSSOP (0.295", 7.50mm Width) package with identical pin assignments and footprints, enabling direct PCB layout compatibility without redesign.
