Key electrical and mechanical differences between the two devices
| Parameter | 83905AGILF | 83905AGILFT | Why it matters |
|---|---|---|---|
| Manufacturer | Renesas Electronics America Inc | Renesas Electronics America Inc | Identical manufacturer ensures the same design, process, and quality standards for both parts. |
| Function / Type | Clock Fanout Buffer / Zero Delay Buffer | Clock Fanout Buffer / Zero Delay Buffer | Both devices perform the same clock distribution function, making them functionally interchangeable. |
| Number of Outputs | 5 | 5 | Matching output count ensures the same number of clock loads can be driven in a target design. |
| Input Type | LVCMOS / LVTTL | LVCMOS / LVTTL | Identical input compatibility allows the same upstream logic to drive either device. |
| Output Type | LVCMOS / LVTTL | LVCMOS / LVTTL | Same output signaling ensures downstream receivers see compatible voltage levels. |
| Supply Voltage | 3.3 V | 3.3 V | Matching supply voltage means no power rail redesign is needed when substituting parts. |
| Operating Temperature Range | -40°C to 85°C | -40°C to 85°C | Identical temperature ratings ensure both parts meet the same environmental requirements. |
| Package / Case | 16-TSSOP | 16-TSSOP | Same package footprint allows drop-in replacement on an existing PCB layout. |
| Packaging | Tube | Tape & Reel | Packaging differs, affecting handling and assembly method; the "T" suffix denotes tape and reel for automated pick-and-place production. |
| Moisture Sensitivity Level (MSL) | MSL 1 (Unlimited) | MSL 1 (Unlimited) | MSL determines floor life and baking requirements before reflow soldering; both share the same rating. |

Frequently asked questions
What is the difference between 83905AGILF and 83905AGILFT?
The 83905AGILF and 83905AGILFT are the same device from Renesas (formerly IDT). The "T" suffix indicates tape-and-reel packaging, while the non-T version is typically supplied in tubes. Both are the 83905A zero-delay clock buffer in a 16-lead TSSOP package.
Are 83905AGILF and 83905AGILFT electrically and functionally identical?
Yes. Both part numbers refer to the same silicon and package. The only difference is the shipping/packaging format, so electrical specifications, pinout, and functional behavior are identical.
Can 83905AGILF and 83905AGILFT be used interchangeably in a design?
Yes, they are interchangeable in terms of form, fit, and function. The choice between them depends on the assembly or procurement preference for tube versus tape-and-reel packaging.
What package do 83905AGILF and 83905AGILFT use?
Both devices are offered in a 16-lead TSSOP package, consistent with the Renesas 83905A datasheet.
What is the function of the 83905A device used in 83905AGILF and 83905AGILFT?
The 83905A is a zero-delay clock buffer designed for clock distribution applications, providing low skew and fanout of a reference clock in systems such as networking, computing, and industrial equipment.
Do 83905AGILF and 83905AGILFT differ in operating temperature range or supply voltage?
No. Because they are the same device, both share the same specified operating temperature range and supply voltage requirements as stated in the Renesas 83905A datasheet.
Which part number should be ordered for automated assembly?
83905AGILFT is the tape-and-reel option, which is generally preferred for automated pick-and-place assembly. 83905AGILF in tubes is typically used for manual handling or prototyping.
