CDC319DB

Overview

The CDC319DB is a fanout buffer and clock distribution integrated circuit manufactured by Texas Instruments. It features a 1:10 input-to-output ratio, converting a single LVTTL input signal into ten LVTTL or TTL outputs. The device supports a maximum operating frequency of 100 MHz and operates within a supply voltage range of 3.135 V to 3.465 V. Designed for surface-mount assembly, it is housed in a 28-pin SSOP package with a width of 5.30 mm. The component functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• 1:10 Fanout Buffer Configuration
• LVTTL Input with LVTTL/TTL Outputs
• Maximum Frequency of 100 MHz
• 28-Pin SSOP Surface-Mount Package

Applications

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

Procurement Notes

Verify the specific package variant against the 28-SSOP specification. Confirm that the application environment remains within the 0°C to 70°C operating temperature limits. Ensure power supply rails are maintained strictly between 3.135 V and 3.465 V to guarantee correct operation at the specified 100 MHz frequency.

Selection Notes

Select this component when a single clock source must drive ten distinct loads using LVTTL or TTL signaling. Verify that the target system does not require differential signaling, as this device uses single-ended inputs and outputs. Confirm that the 100 MHz maximum frequency meets the system's timing requirements.

Part Context

This part belongs to the Texas Instruments clock buffer and driver category. It serves as a signal distribution element within digital electronics, specifically designed to maintain signal integrity while expanding one input line into multiple output lines for downstream logic components.

Replacement Considerations

Check for compatible 1:10 LVTTL fanout buffers from other manufacturers. Ensure replacement parts match the 28-SSOP footprint and support the required 3.3 V nominal supply voltage range.
