ML6426CS1

Overview

The ML6426CS1 is a triple video filter integrated circuit manufactured by Fairchild Semiconductor. It implements a fourth-order Butterworth low-pass and band-pass filter configuration with a cut-off frequency of 6.7MHz. The device is housed in a 16-SOIC package and features buffered outputs for signal integrity. It operates at a supply voltage of 5V, drawing approximately 12mA of supply current during typical operation.

Feature Summary

• Triple video filter architecture with dedicated buffered outputs
• Fourth-order Butterworth response for precise signal filtering
• Integrated low-pass and band-pass filtering capabilities

Applications

• Video signal processing circuits
• Baseband video filtering applications
• Signal conditioning for video interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status as indicated in official documentation. Ensure the 16-SOIC package variant matches system board layout requirements. Validate that the 6.7MHz cut-off specification aligns with target video bandwidth constraints before procurement.

Selection Notes

Select this component when a fourth-order Butterworth response is required for video signals near 6.7MHz. The buffered output design simplifies interface to subsequent stages without loading effects. Consider the 12mA supply current draw for power budget calculations in 5V systems. Verify compatibility with existing video infrastructure signal levels.

Part Context

This part belongs to the ML6426 family of triple video filters from Fairchild Semiconductor. Variants within this family share similar architectures but differ in passband cut-off frequencies. The ML6426CS1 specifically targets applications requiring a 6.7MHz bandwidth with high-order attenuation characteristics.

Replacement Considerations

Consult official substitution lists for compatible parts within the ML6426 series. Verify pinout and electrical parameter equivalence before replacing. No specific substitute part numbers are confirmed in public documentation.
