NB2305AI1DTR2G

Overview

The NB2305AI1DTR2G is a zero-delay PLL clock buffer manufactured by onsemi. It operates within a supply voltage range of 3 V to 3.6 V, with a nominal operating voltage of 3.3 V. The device supports an output frequency range from 15 MHz to 133 MHz and contains one circuit. It utilizes silicon technology and features CMOS input and output interfaces. The component is designed for surface mount installation in an 8-TSSOP package (0.173", 4.40mm width). It functions across an extended temperature range of -40°C to +85°C.

Feature Summary

• Zero-delay buffer architecture with 1:5 input-to-output ratio
• Supports frequencies up to 133 MHz with 3.3 V operation
• CMOS compatible inputs and outputs
• Available in 8-TSSOP surface-mount packaging

Applications

• Clock distribution in high-speed digital systems
• Buffering reference clocks for data converters
• Timing synchronization in communication equipment

Procurement Notes

This component is identified as obsolete or end-of-life. Manufacturers may discontinue production, requiring verification of current availability through authorized distributors. Sourcing should focus on existing stock or qualified replacement parts that meet the same electrical specifications and pinout requirements.

Selection Notes

Select this part when a single-ended CMOS clock signal requires buffering into five identical outputs with minimal propagation delay skew. Ensure the design environment supports the 3.3 V logic level and the TSSOP-8 footprint. Verify that the required frequency does not exceed 133 MHz and that the ambient temperature remains within the specified industrial range.

Part Context

The NB2305AI1DTR2G belongs to the NB2305A series of zero-delay buffers. It shares functional similarities with other models in the NB230x family, such as the NB2304A and NB2308A, which offer different output counts. The 'I' suffix typically denotes industrial temperature range performance, while 'DTR2G' indicates the specific tape-and-reel packaging configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available documentation. Designers should consult manufacturer cross-reference tools for equivalent zero-delay buffers with matching 1:5 ratios and 3.3 V operation.
