CDC319DBR

Overview

The CDC319DBR is a 1-line to 10-line clock driver manufactured by Texas Instruments. It functions as a fanout buffer with a 1:10 input-to-output ratio, designed for distributing clock signals in digital systems. The device accepts LVTTL inputs and provides LVTTL or TTL outputs. It operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 100 MHz. The component is housed in a 28-SSOP package (5.30mm width) and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• 1-to-10 line clock distribution capability
• LVTTL input with LVTTL/TTL output compatibility
• Maximum operating frequency of 100 MHz
• Surface mount 28-SSOP package

Applications

• Clock signal distribution in high-speed digital circuits
• Fanout buffering for LVTTL/TTL logic systems
• System timing architecture in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging details such as Tape & Reel versus Bulk quantities. Ensure the selected variant matches the required voltage and temperature specifications for the target application environment.

Selection Notes

Select this component when a single clock source needs to drive ten separate LVTTL or TTL loads. Confirm that the system power supply remains within the 3.135V to 3.465V range. Verify that the 0°C to 70°C commercial temperature grade meets the operational requirements of the final assembly.

Part Context

The CDC319 belongs to the family of clock drivers from Texas Instruments. Variants such as CDC319DB and CDC319DB.B share similar functional descriptions as 1-line to 10-line clock drivers with I2C control interfaces in some documentation contexts, though the core CDC319 model is defined here by its direct LVTTL/TTL interface characteristics.
