CD4097BMG4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD4097BMG4 is a dual differential multiplexer manufactured by Texas Instruments, belonging to the CD4000B series of CMOS logic devices. It integrates two independent 8-to-1 multiplexing circuits within a single 24-pin Small Outline Integrated Circuit (SOIC) package. The device operates on a single power supply ranging from 3V to 18V and supports an operating temperature range of -55°C to 125°C. Key electrical specifications include a maximum on-resistance of 240 ohms, a channel-to-channel matching of 5 ohms, and a -3dB bandwidth of 20MHz. The component features low leakage current with a maximum off-state drain current of 100nA and low capacitance values of 0.2pF and 35pF for off-state channels.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current documentation to confirm RoHS compliance status and lead times, as this suffix indicates environmental compliance. Confirm availability through authorized distributors, noting that older variants may be obsolete or subject to long lead times. Ensure the 24-SOIC package dimensions match the target PCB footprint requirements before ordering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the CD4097BMG4 when dual differential 8:1 multiplexing is required within a compact surface-mount package. Compare the 240-ohm on-resistance and 20MHz bandwidth against application signal integrity needs. Consider the -55°C to 125°C operating range for harsh environment suitability. Verify that the single-supply voltage range of 3V to 18V aligns with the system power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

The CD4097BMG4 is part of the broader CD4000B series of CMOS logic integrated circuits produced by Texas Instruments. This series is known for its compatibility with standard CMOS logic levels and wide operating voltage ranges.
