PI6CV304LE Clock Fanout Buffer - Equivalent & Substitute Parts

Part Overview

The PI6CV304LE is a Clock Fanout Buffer (Distribution) IC manufactured by Diodes Incorporated, designed for 1:4 clock distribution at 160 MHz maximum frequency. This component is classified as Obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part operates with CMOS/TTL inputs and LVCMOS outputs in an 8-TSSOP surface mount package, suitable for applications requiring reliable clock signal distribution across multiple endpoints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI6CV304LE are qualified based on the following critical parameters that determine functional compatibility:

Core Substitution Criteria:

• Fanout Buffer (Distribution) type with 1:4 input-to-output ratio
• 8-TSSOP surface mount package (0.173", 4.40mm Width)
• Operating temperature range: -40°C ~ 85°C
• Supply voltage compatibility within 3V ~ 3.6V range
• LVCMOS output capability
• RoHS3 compliance

Substitutes are grouped into two categories:

1. Direct Pin-Compatible Substitutes - Identical electrical specifications and packaging
2. Functional Equivalents - Same 1:4 fanout topology with compatible frequency ranges and voltage specifications

The PI6CV304LEX (Diodes Incorporated) represents a direct substitute with identical specifications but Active product status and Tape & Reel packaging. The NB3N2304NZDTG (onsemi) and 2304NZGI-1LF (Renesas) provide functional equivalence with 140 MHz maximum frequency. The 5PB1104PGGI (Renesas) offers enhanced frequency capability at 200 MHz with extended voltage range compatibility.

Parameter Comparison

Engineering Selection Recommendations

PI6CV304LEX - Recommended as the primary substitute. Manufactured by Diodes Incorporated with identical electrical specifications to the PI6CV304LE. Active product status ensures long-term availability. Tape & Reel packaging supports automated assembly processes. ROHS3 compliance and MSL-1 rating match the original part requirements.

5PB1104PGGI - Suitable for applications where higher frequency capability (200 MHz) is beneficial. Renesas Electronics Corporation active product status provides supply continuity. Extended voltage range (1.71V ~ 3.465V) offers design flexibility. ROHS3 compliant with MSL-1 rating. Frequency headroom above the original 160 MHz specification supports margin in clock distribution applications.

NB3N2304NZDTG - Functional equivalent from onsemi with active product status. 140 MHz maximum frequency operates within acceptable margin for most 160 MHz applications. LVCMOS/LVTTL input and output flexibility. MSL-3 rating requires controlled moisture exposure during storage and handling compared to MSL-1 alternatives.

2304NZGI-1LF - Renesas Electronics Corporation part with 140 MHz specification. Obsolete product status limits future availability. MSL-1 rating and ROHS3 compliance match original specifications. Suitable only for existing inventory management or legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can PI6CV304LEX directly replace PI6CV304LE without circuit modifications?

A: Yes. PI6CV304LEX is a direct substitute with identical electrical specifications, package type, and pin configuration. The only difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard). No circuit modifications are required.

Q: What is the impact of using NB3N2304NZDTG with its 140 MHz maximum frequency instead of 160 MHz?

A: The 140 MHz specification provides 87.5% of the original 160 MHz capability. For clock distribution applications operating below 140 MHz, this part functions identically. Applications requiring frequencies between 140-160 MHz require evaluation of actual operating conditions and timing margins.

Q: Why does 5PB1104PGGI have a lower voltage supply range (1.71V ~ 3.465V) compared to PI6CV304LE (3V ~ 3.6V)?

A: The 5PB1104PGGI supports a wider voltage range that encompasses the original specification. The lower minimum (1.71V) and higher maximum (3.465V) provide greater design flexibility while remaining compatible with 3V ~ 3.6V supply systems.

Q: What is the significance of MSL-3 rating on NB3N2304NZDTG versus MSL-1 on other substitutes?

A: MSL-3 (168 Hours) requires moisture bake-out procedures before soldering if the component has been exposed to humidity for extended periods. MSL-1 (Unlimited) has no moisture sensitivity restrictions. For high-volume production, MSL-1 parts reduce handling complexity and risk of moisture-related failures.

Q: Are all substitute parts available in 8-TSSOP package only?

A: Yes. All listed substitutes are specified in 8-TSSOP (0.173", 4.40mm Width) surface mount package, maintaining mechanical and electrical compatibility with the original PI6CV304LE footprint.

Q: Which substitute offers the best long-term availability?

A: PI6CV304LEX and 5PB1104PGGI both have Active product status from established manufacturers (Diodes Incorporated and Renesas Electronics Corporation), ensuring continued production and supply chain support.
