8343AYI-01LF

Overview

The IDT 8343AYI-01LF is a low skew, 1-to-16 LVCMOS/LVTTL fanout buffer belonging to the HiPerClockS family. It features a single-ended clock input accepting LVCMOS or LVTTL levels and provides sixteen outputs. The device supports full 3.3V, full 2.5V, and mixed 3.3V input with 2.5V output supply modes over the commercial temperature range. Key electrical specifications include a maximum output frequency of 200MHz, a maximum output skew of 250ps, and a maximum part-to-part skew of 700ps.

Feature Summary

• 16 LVCMOS/LVTTL outputs with dual output enable inputs for flexible 1-to-16 or 1-to-8 configurations
• Maximum output frequency of 200MHz with guaranteed output and part-to-part skew characteristics
• All inputs are 5V tolerant, supporting mixed voltage operation modes

Applications

• Clock distribution systems requiring well-defined performance and repeatability
• Low skew buffering for LVCMOS and LVTTL logic interfaces
• High-performance clock solutions in commercial electronic equipment

Procurement Notes

Verify RoHS compliance status as the 'LF' suffix typically indicates lead-free composition, though specific datasheets should be consulted for final confirmation. Ensure the operating environment remains within the commercial temperature range and that supply voltages match the supported 3.3V or 2.5V configurations.

Selection Notes

Select this component when a single-ended LVCMOS or LVTTL source requires expansion into sixteen buffered signals. Verify that the required skew performance meets the 250ps output skew limit. Consider the 5V tolerant inputs if interfacing with legacy logic levels while maintaining lower voltage core operation.

Part Context

This part is a member of the HiPerClockS family from Integrated Device Technology (IDT), now part of Renesas. It serves as a specialized fanout buffer designed to maintain signal integrity across multiple loads. The 8343 series is distinct from differential input drivers like the 858020, focusing on single-ended conversion and distribution.

Replacement Considerations

Direct replacements must support 16 LVCMOS/LVTTL outputs, 200MHz frequency, and similar skew specifications. Check for pin compatibility and voltage tolerance requirements. Note that some variants may differ in package type or temperature rating.
