DG406EY

Overview

The DG406EY is a high-speed, low-power CMOS analog multiplexer manufactured by Harris Corporation. It features a single 16-channel or differential 8-channel configuration with a 1x16:1 switch topology. Key electrical parameters include a typical on-resistance (RDS(ON)) of 50 ohms, a maximum leakage current of 0.04 nA, and a drain capacitance of 180 pC. The device exhibits fast switching times with a turn-on time (TON) of 150 ns and a turn-off time (TOFF) of 70 ns. Charge injection is specified at 40 pC. These characteristics support its use in precision data acquisition and communication systems.

Procurement Notes

Verify the manufacturer source carefully, as Harris Corporation's semiconductor assets were acquired by Analog Devices Inc. Ensure the component documentation aligns with ADI specifications if sourced from modern distributors. Confirm that the 'E' suffix denotes the correct temperature range and package variant required for your specific design constraints before finalizing procurement.

Selection Notes

Select this component when a high channel count (16 channels) is required in a compact form factor. It is appropriate for designs needing low power dissipation alongside moderate switching speeds. Verify that the 50-ohm on-resistance and 180-pF drain capacitance meet the bandwidth and loading requirements of the connected analog signals compared to lower-capacitance alternatives.

Part Context

This part belongs to the family of CMOS analog multiplexers designed for general-purpose signal routing. It provides a cost-effective solution for managing multiple input lines in embedded systems. The device integrates control logic and analog switches into a single monolithic structure, simplifying board layout and reducing the component count required for complex switching matrices.

Replacement Considerations

Analog Devices Inc. acquired Harris Semiconductor. Check for direct cross-references such as the ADG406 series. Verify pin compatibility and electrical parameter equivalence, particularly regarding on-resistance and switching speed, before substituting.
