• Provides low skew signal buffering for precise timing distribution
• Supports up to nine LVCMOS/LVTTL outputs for fanout applications
• Designed to drive 50Ω series terminated loads

Applications

• High performance clock distribution systems
• Timing signal buffering in digital circuits
• LVCMOS/LVTTL interface applications

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to ensure correct package type and temperature grade. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing process. Check for any specific handling instructions related to the Moisture Sensitivity Level (MSL) rating during storage and assembly. Ensure compatibility with your board design regarding the 32-lead carrier configuration.

Selection Notes

Select this component when a single clock source must be distributed to multiple LVCMOS or LVTTL destinations with minimal timing skew. It is suitable for designs requiring a maximum frequency of 110MHz. Consider the operating temperature range of -40°C to 85°C for environmental constraints. Evaluate the need for driving 50Ω series terminated loads to determine if this buffer architecture fits the impedance requirements of the target circuit.
