87004BGI-03LFT

Overview

The ISL87004I-03 (commercially listed as 87004BGI-03LFT) is a low skew LVCMOS/LVTTL fanout buffer and divider manufactured by Integrated Device Technology, now part of Renesas Electronics. This device features selectable clock inputs that accept single-ended input levels and includes an output enable pin to control active or high-impedance states. It is characterized for operation at 3.3V, 2.5V, and mixed voltage modes including 3.3V/1.8V and 2.5V/1.8V combinations. The component provides division ratios of ÷1, ÷2, ÷3, ÷4, ÷5, ÷6, ÷8, and ÷16 across four outputs.

Feature Summary

• Low skew LVCMOS/LVTTL fanout buffer/divider with guaranteed bank, output, and part-to-part skew characteristics
• Selectable clock inputs accepting single-ended signals with output enable control
• Supports multiple supply operating modes: 3.3V, 2.5V, and mixed 3.3V/2.5V, 3.3V/1.8V, 2.5V/1.8V
• Provides frequency division options of ÷1 through ÷16

Applications

• Applications demanding well-defined performance and repeatability in clock distribution
• Systems requiring low skew clock buffering for LVCMOS/LVTTL interfaces
• Mixed voltage environments utilizing 3.3V, 2.5V, or 1.8V logic families

Procurement Notes

Verify the manufacturer designation carefully, as the part was originally produced by Integrated Device Technology (IDT) before its acquisition by Renesas. Confirm the specific suffix 'LFT' indicates lead-free compliance and RoHS status. Check for Product Change Notices (PCN) regarding label updates or end-of-life declarations, as IDT/Renesas components often undergo packaging or labeling modifications that do not alter electrical function but may affect sourcing documentation.

Selection Notes

Select this component when low skew and precise timing repeatability are critical for clock distribution networks. Ensure the system design supports the required mixed voltage supply configurations if using non-standard logic levels like 1.8V. Verify that the single-ended input requirement aligns with the source clock driver capabilities. The device is housed in a TSSOP-20 package; confirm board space constraints accommodate this form factor.

Part Context

This part belongs to the 87004 series of clock buffers and dividers. It is distinct from Renesas power management ICs such as the ISL8700 supervisor series or the ISL6731 PFC controller, which share similar alphanumeric prefixes but serve entirely different functions within power electronics rather than digital signal processing.
