CDC2351DB

Overview

The Texas Instruments CDC2351DB is a single-circuit fanout buffer designed for clock distribution applications. It accepts a single-ended LVTTL input and provides ten single-ended LVTTL outputs. The device supports maximum operating frequencies of 100 MHz and functions within a supply voltage range of 3V to 3.6V. Packaged in a 24-SSOP surface-mount case with a width of 5.30mm, it operates reliably across an industrial temperature range of 0°C to 70°C.

Feature Summary

• Single-ended LVTTL input to ten single-ended LVTTL output configuration
• Maximum operating frequency of 100 MHz
• Supply voltage range of 3V to 3.6V
• Surface mount 24-SSOP package (5.30mm width)

Applications

• Clock distribution networks requiring signal buffering
• Digital systems utilizing LVTTL logic families
• Board-level timing synchronization

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape/reel versus tube packaging options. Ensure the selected variant matches the required operating temperature range and electrical specifications for the target design environment.

Selection Notes

Select this component when a single-ended LVTTL source must drive multiple LVTTL loads. Confirm that the system power supply remains within the 3V to 3.6V window. Verify that the 100 MHz frequency limit meets the system clock requirements and that the 24-SSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the CDC235x series of clock buffers manufactured by Texas Instruments. These devices are engineered to provide high-performance fanout capabilities for digital clock signals, ensuring signal integrity across multiple destinations in complex electronic systems.

Replacement Considerations

Check for pin-compatible alternatives such as the CDC351IDW or CDC2351DR if different packaging or extended temperature ranges are required. Verify electrical compatibility before substitution.
