CD4067BM

CD4067BM Description

The CD4067BM from Texas Instruments is a high-performance 16:1 analog multiplexer/demultiplexer IC designed for precision signal routing in low-to-medium frequency applications. Housed in a 24-SOIC package, it features a wide supply voltage range (3V to 18V) and low on-state resistance (240Ω max), making it suitable for both industrial and consumer electronics. With a -3dB bandwidth of 14MHz and minimal channel-to-channel matching (ΔRon: 5Ω), it ensures consistent signal integrity across all channels. The device is RoHS3 compliant and has a low leakage current (100nA max), enhancing reliability in battery-powered systems.
