Each switch passes signals rail-to-rail, and the bilateral topology lets you use them as multiplexers, sample-hold gates, or modulator switches without worrying about signal polarity. The 4000B series CMOS construction keeps leakage low at high temperature — a practical advantage over older 4000A parts when the ambient hits 125°C. Housed in a 14-TSSOP (4.40 mm width) surface-mount package, the CD4066BPWR fits on compact PCBs where board area is tight. The TSSOP footprint is standard across many 14-pin analog switches, so swapping to a pin-compatible alternative (e.g., a 74HC4066 in the same package) is straightforward if supply dictates a change. For new designs, there is no LTB risk and the part can be qualified into the BOM with confidence.","metaTitle":"CD4066BPWR Bilateral FET Switch, 3V-18V, 14-TSSOP","metaDescription":"Texas Instruments CD4066BPWR bilateral FET switch, quad SPST, 3V to 18V supply, -55°C to 125°C, 14-TSSOP.
