CDC2351DWR

Overview

The CDC2351DWR is a single-circuit fanout buffer and clock distribution integrated circuit manufactured by Texas Instruments. It features a 1:10 input-to-output ratio, designed to drive multiple loads from a single source. The device operates with LVTTL logic levels for both input and output signals. It supports a maximum operating frequency of 100 MHz and functions within a supply voltage range of 3 V to 3.6 V. The component is housed in a 24-SOIC package (0.295 inch width) and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• 1:10 Fanout Buffer Configuration
• 100 MHz Maximum Frequency
• LVTTL Input/Output Logic Levels
• 3V to 3.6V Supply Voltage Range

Applications

• Clock distribution networks requiring signal splitting
• Digital systems utilizing LVTTL logic interfaces
• Board-level timing synchronization circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type, as 'DWR' typically indicates Tape & Reel but official datasheets should be consulted for exact reel specifications and quantity per unit.

Selection Notes

Select this component when a single clock source must drive up to ten downstream LVTTL loads. Ensure the system power supply remains stable between 3 V and 3.6 V. Confirm that the required operating environment falls within the commercial temperature range of 0°C to 70°C.

Part Context

This part belongs to the clock buffer and driver category within Texas Instruments' portfolio. It serves as a distribution element in digital timing architectures, distinct from oscillators or multi-phase generators, focusing solely on signal integrity and load driving capability for LVTTL standards.

Replacement Considerations

Consult the manufacturer's pin-to-pin compatibility guide for direct replacements. Verify that any substitute maintains the 1:10 ratio, 100 MHz speed, and LVTTL compatibility.
