CD4097BE

CD4097BE Description

The CD4097BE is a dual 8:1 multiplexer/demultiplexer integrated circuit (IC) designed by Texas Instruments. This through-hole mounted IC is housed in a tube package and features a supply voltage range of 3V to 18V. It is designed to offer efficient signal routing with a maximum on-state resistance (Ron) of 240 ohms and a channel-to-channel matching (ΔRon) of 5 ohms. The CD4097BE also boasts low leakage current (IS(off)) of up to 100nA and a -3dB bandwidth of 20MHz. The channel capacitance is specified as 0.2pF for CS(off) and 35pF for CD(off). Despite its obsolescence, the CD4097BE remains a reliable choice for applications requiring robust signal switching and routing. It is REACH unaffected and RoHS3 compliant, ensuring environmental and regulatory compliance.
