PI6C182AHE Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The PI6C182AHE is a Clock Fanout Buffer (Distribution) IC manufactured by Diodes Incorporated, designed for 1:10 clock distribution at 125 MHz with TTL input/output compatibility. This part is classified as Obsolete, making identification of active equivalent alternatives essential for new designs and production continuity. The substitute parts listed maintain functional compatibility through matching core distribution ratios, package form factors, and electrical operating parameters while offering active product status from established manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI6C182AHE is determined by the following critical parameters:

• Distribution Ratio: 1:10 configuration (one input, ten outputs)
• Package Compatibility: 28-SSOP (0.209", 5.30mm Width) surface mount form factor
• Supply Voltage Range: 3.135V ~ 3.465V operating window
• Operating Temperature Range: 0°C ~ 70°C
• Logic Compatibility: TTL input and output levels
• Environmental Compliance: ROHS3 Compliant status

The CDC319DB and CDC319DBR from Texas Instruments satisfy all substitution criteria. Both parts maintain the 1:10 distribution ratio, identical package geometry, matching supply voltage specifications, and equivalent operating temperature range. The CDC319DB and CDC319DBR feature LVTTL input with TTL/LVTTL output capability, providing backward compatibility with TTL-level signals while supporting lower-voltage logic families. Both substitute parts are classified as Active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Both CDC319DB and CDC319DBR are qualified substitutes for the obsolete PI6C182AHE. Selection between the two Texas Instruments alternatives depends on procurement and assembly requirements:

CDC319DB is supplied in bulk packaging and maintains full electrical equivalence with identical specifications to CDC319DBR.

CDC319DBR is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly operations and high-volume production environments.

Both parts carry Active product status, ensuring long-term availability and manufacturing support. ROHS3 compliance and MSL 1 (Unlimited) ratings match the original part specifications. The maximum frequency specification of 100 MHz on the substitute parts remains within acceptable margins for applications originally designed for the PI6C182AHE's 125 MHz rating, provided system timing requirements do not mandate operation at frequencies exceeding 100 MHz.

Frequently Asked Questions (FAQ)

Q: Can CDC319DB and CDC319DBR be used interchangeably with PI6C182AHE?

A: Yes. Both Texas Instruments parts maintain the critical substitution parameters: 1:10 distribution ratio, 28-SSOP package geometry, 3.135V–3.465V supply voltage range, and 0°C–70°C operating temperature. The primary difference is packaging format (bulk versus Tape & Reel).

Q: What is the difference between CDC319DB and CDC319DBR?

A: CDC319DB is supplied in bulk packaging. CDC319DBR is supplied in Tape & Reel (TR) format for automated assembly. Electrical specifications are identical.

Q: Does the 100 MHz maximum frequency of the substitute parts affect compatibility?

A: The substitute parts are rated for 100 MHz maximum frequency, compared to 125 MHz for the PI6C182AHE. Substitution is appropriate for applications operating at or below 100 MHz. Applications requiring operation above 100 MHz require design review.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both CDC319DB and CDC319DBR are ROHS3 Compliant, matching the compliance status of the original PI6C182AHE.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts?

A: Both CDC319DB and CDC319DBR carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are the input/output logic levels compatible?

A: The substitute parts feature LVTTL input with TTL/LVTTL output capability. This configuration provides backward compatibility with TTL-level signals from the original PI6C182AHE while supporting lower-voltage logic families.
