CDC328ADBRG4

Overview

The CDC328ADBRG4 is a fanout buffer and clock distribution integrated circuit manufactured by Texas Instruments. It provides a single input to six output configuration, designed for high-speed signal buffering with a maximum frequency of 100 MHz. The device operates on a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output logic levels. Packaged in a 16-SSOP surface-mount case, it is rated for an operating temperature range of -40°C to +85°C. This component serves as a dedicated clock driver for distributing timing signals within electronic systems.

Feature Summary

• Single-to-six (1:6) fanout buffer configuration
• Maximum operating frequency of 100 MHz
• TTL-compatible input and output logic levels
• Operates on a 4.75 V to 5.25 V power supply

Applications

• Clock distribution networks requiring signal buffering
• High-speed digital system timing architectures
• Embedded systems utilizing TTL-based clock sources

Procurement Notes

Verify the specific ordering suffix 'G4' against manufacturer documentation to confirm compliance details and package variations. Ensure the required quantity aligns with the Tape & Reel (TR) packaging format specified for this part number. Confirm that the 16-SSOP footprint matches the target PCB design constraints before procurement.

Selection Notes

Select this component when a 1:6 fanout ratio is required for TTL-level clock signals up to 100 MHz. The fixed 5V supply requirement (4.75–5.25 V) distinguishes it from lower-voltage LVCMOS drivers. Verify that the 16-SSOP package dimensions fit the available board space and that the -40°C to +85°C industrial temperature range meets the operational environment specifications.

Part Context

This part belongs to the CDC328A series of clock drivers. The 'G4' suffix typically indicates lead-free and RoHS-compliant manufacturing variants within the Texas Instruments portfolio. It functions specifically as a buffer rather than a programmable clock generator or multiplier.

Replacement Considerations

Check for CDC328ADBRE4 as a potential equivalent variant within the same family. Verify pin compatibility and electrical parameters against the original datasheet before substituting.
