PI6C2409-1HLE Zero Delay Buffer IC Equivalent & Substitute Parts

Part Overview

The PI6C2409-1HLE is a Zero Delay Buffer IC manufactured by Diodes Incorporated, designed for clock/timing applications requiring 133MHz operation with 1:9 input-to-output ratio. This part operates with TTL input/output levels and a supply voltage range of 3V to 3.6V in a 16-TSSOP surface mount package.

The PI6C2409-1HLE is classified as obsolete. Equivalent and substitute parts from Renesas Electronics Corporation are available as active alternatives, providing functional compatibility while maintaining the same electrical and mechanical specifications required for direct replacement in clock distribution and timing circuits.

Substitute Part Grouping Explanation

Substitution of the PI6C2409-1HLE is determined by strict equivalence in the following electrical and mechanical parameters:

Maximum frequency: 133MHz
Input-to-output ratio: 1:9
Supply voltage range: 3V to 3.6V
Package: 16-TSSOP surface mount
Logic level compatibility: TTL/LVTTL input with TTL/LVTTL or CMOS output capability
Compliance: ROHS3 and MSL 1 rating

Renesas Electronics Corporation manufactures functionally equivalent parts across multiple product lines (2309, 2309A, 23S09 series) available in two packaging formats: Tube and Tape & Reel (TR). All substitute parts maintain identical electrical performance at 133MHz with 1:9 buffering.

Operating temperature range varies between substitute options: parts designated with temperature range 0°C to 70°C provide direct thermal compatibility with the original PI6C2409-1HLE, while extended-range variants (-40°C to 85°C) offer broader environmental operation.

Engineering Selection Recommendations

All listed Renesas Electronics substitute parts are active products with ROHS3 compliance and MSL 1 rating, matching the compliance profile of the obsolete PI6C2409-1HLE.

For applications requiring thermal compatibility with the original 0°C to 70°C operating range, select from the 2309-1HPGG, 2309-1HPGG8, 2309A-1HPGG, or 2309A-1HPGG8 variants. These parts are designated as manufacturer-recommended replacements.

For applications requiring extended operating temperature range (-40°C to 85°C), select from the 2309-1HPGGI, 2309-1HPGGI8, 2309A-1HPGGI, 2309A-1HPGGI8, 23S09-1HPGGI, or 23S09-1HPGGI8 variants.

Packaging format selection depends on procurement and assembly requirements: Tube packaging for lower-volume applications, Tape & Reel for automated assembly processes.

The 23S09 series variants provide CMOS output capability in addition to LVTTL, offering expanded output compatibility for mixed-signal applications.

Frequently Asked Questions (FAQ)

Q: Can the PI6C2409-1HLE be directly replaced with any of the listed Renesas parts?

A: Yes. All listed Renesas parts maintain identical electrical specifications at 133MHz with 1:9 buffering, 3V to 3.6V supply voltage, and 16-TSSOP surface mount packaging. The primary selection criterion is operating temperature range and packaging format.

Q: What is the difference between the 2309, 2309A, and 23S09 product lines?

A: All three product lines are functionally equivalent zero delay buffers at 133MHz with 1:9 ratio. The 23S09 series provides dual output capability (CMOS and LVTTL), while 2309 and 2309A variants provide LVTTL output only. Selection depends on output logic level requirements.

Q: Does operating temperature range affect electrical performance?

A: No. The 0°C to 70°C and -40°C to 85°C variants maintain identical electrical performance across their respective operating ranges. Temperature range selection is based on application environmental requirements.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Both formats contain identical parts. Tube packaging is suitable for manual assembly and lower-volume applications. Tape & Reel packaging is designed for automated pick-and-place assembly equipment and higher-volume production.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed Renesas substitute parts carry ROHS3 compliance and MSL 1 rating, matching the compliance requirements of the original PI6C2409-1HLE.

Q: Which substitute part is recommended as the primary replacement?

A: The 2309-1HPGG and 2309-1HPGG8 variants are designated as manufacturer-recommended replacements, maintaining the original 0°C to 70°C operating temperature range while providing active product status and full availability.
