CDC341DWG4

Overview

The CDC341DWG4 is a single-channel fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It accepts a TTL input signal and provides eight TTL outputs with a 1:8 splitting ratio. The device supports a maximum operating frequency of 80 MHz and functions within a supply voltage range of 4.75V to 5.25V. It is housed in a 20-SOIC surface-mount package with a width of 7.50mm. The component is rated for an industrial operating temperature range of 0°C to 70°C.

Feature Summary

• Single circuit configuration providing one-to-eight (1:8) fanout capability
• Supports maximum clock frequencies up to 80 MHz
• Compatible with TTL logic levels for both input and output signals
• Operates on a standard 5V supply rail ranging from 4.75V to 5.25V

Applications

• Clock signal distribution in digital systems
• Buffering timing signals for multiple loads
• Industrial control system timing networks

Procurement Notes

Verify the specific suffix G4 against the manufacturer's current documentation to confirm RoHS compliance status and lead times. Confirm that the 0°C to 70°C commercial temperature grade meets the operational requirements of the target environment, as industrial variants may offer wider thermal ranges.

Selection Notes

Select this component when a single-ended TTL source must drive eight distinct TTL destinations without inversion. Ensure the design operates within the 4.75V to 5.25V power supply constraints. Verify that the 80 MHz frequency limit satisfies the system clock speed requirements and that the 20-SOIC footprint fits the PCB layout constraints.

Part Context

This part belongs to the CDC3xx series of clock buffers and drivers from Texas Instruments. These devices are engineered to maintain signal integrity while distributing clock signals across complex digital circuits. The G4 suffix typically indicates a lead-free and RoHS-compliant version of the base CDC341DW model.

Replacement Considerations

Direct pin-compatible replacements include the CDC341DW. Verify electrical specifications such as propagation delay and output drive strength against the original design requirements before substitution.
