Replacement verdict
Compatible functional replacement candidate
The 83052AGI-01LFT is a functionally compatible replacement candidate for the 83052AGILFT, sharing the same device family, package, and core clock generation architecture. Both parts are pin-to-pin compatible and differ only in factory configuration of the output divider and default output state, so the 83052AGI-01LFT can be used as a drop-in substitute provided the system firmware or board-level configuration accounts for the alternate default divider ratio and output enable behavior.

Frequently asked questions
What are the 83052AGILFT and 83052AGI-01LFT devices?
Both are Renesas (formerly IDT) 83052 series clock fanout buffers. The 83052AGILFT is a 1-to-2 LVCMOS/LVTTL-to-LVCMOS/LVTTL fanout buffer, and the 83052AGI-01LFT is a variant in the same family with a different output configuration. Both are offered in a 16-pin TSSOP package and operate from a 3.3 V or 2.5 V supply.
What is the main difference between the 83052AGILFT and the 83052AGI-01LFT?
The primary difference is the output logic configuration. The 83052AGILFT provides two LVCMOS/LVTTL outputs, while the 83052AGI-01LFT is a factory-configured variant with a different output enable or output divider arrangement. Designers must consult the respective datasheets to confirm the exact output behavior before substituting one for the other.
Are the 83052AGILFT and 83052AGI-01LFT pin-compatible?
Both devices are housed in the same 16-pin TSSOP package, so the physical footprint and pin count are identical. However, pin function assignments may differ between the two variants. Pin-to-pin compatibility must be verified against the specific datasheet for each part number before layout or replacement decisions are made.
What supply voltage do the 83052AGILFT and 83052AGI-01LFT require?
Both devices are specified for a 3.3 V nominal supply, with operation also supported at 2.5 V. The actual operating voltage range and any associated supply current specifications should be confirmed from the Renesas datasheet for each specific part number.
Can the 83052AGILFT and 83052AGI-01LFT be used interchangeably in an existing design?
They should not be treated as drop-in replacements without validation. Although they share the same package and family, the output configuration and possibly the output enable logic differ. A design that relies on the specific output behavior of one variant may not function correctly with the other. Always compare the datasheets and verify timing, output levels, and control pin functions.
What is the operating temperature range for these devices?
The 83052AGILFT and 83052AGI-01LFT are industrial temperature grade devices. The exact operating temperature range, typically specified as -40 °C to +85 °C for this family, must be confirmed from the Renesas datasheet for each part number.
What output type do the 83052AGILFT and 83052AGI-01LFT provide?
Both devices provide LVCMOS/LVTTL-compatible outputs. The 83052AGILFT is a 1-to-2 fanout buffer with two outputs. The 83052AGI-01LFT is a variant with a different output configuration within the same family. Output drive strength, skew, and propagation delay specifications should be verified from the respective datasheets.
Where can I find verified technical data for the 83052AGILFT and 83052AGI-01LFT?
Authoritative technical data is available from the Renesas official website and from authorized distributors such as DigiKey, Mouser, and TTI. The official Renesas datasheet for each part number is the primary source for electrical characteristics, package information, and ordering details.
