DG271BCJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG271BCJ-E3 is a CMOS analog switch IC manufactured by Vishay Siliconix, featuring four single-pole single-throw (SPST) channels. It operates within a supply voltage range of 0°C to +70°C and utilizes a 16-pin PDIP package for through-hole mounting. The device supports dual supply configurations with voltages up to ±15V. Key electrical specifications include a maximum on-resistance of 50 Ohms, a maximum power dissipation of 470 mW, and a typical off-isolation of -80 dB. The component is designed for general-purpose signal switching applications requiring low distortion and high reliability.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix E3 confirms RoHS compliance status before integration. Confirm that the PDIP-16 package aligns with existing PCB footprint designs. Check current lifecycle status as older components may face discontinuation risks. Ensure supply chain stability for long-term production requirements given potential obsolescence trends.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog paths are required in a through-hole design. Compare on-resistance values against application tolerance limits for signal integrity. Evaluate thermal dissipation capabilities relative to expected load currents. Consider alternative packages if surface-mount space constraints exist in the final assembly.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of analog switches from Vishay Siliconix, known for robust CMOS technology. It serves as a legacy option for designs transitioning from older discrete switching solutions. The BCJ variant specifically denotes the plastic DIP package configuration, distinguishing it from SOIC or TSSOP alternatives within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements may include other Vishay DG271 variants with different packaging such as DG271BDY for surface mount applications. Verify equivalent electrical parameters like on-resistance and supply voltage ranges when substituting. Cross-reference datasheets to ensure control logic compatibility and thermal performance match original design intent.
