CD4052BPWR

CD4052BPWR is a Texas Instruments dual 4:1 analog multiplexer/demultiplexer in a TSSOP-16 package — two independent four-channel switches sharing address lines, with 125 Ω typical on-resistance, 18 pF typical on-capacitance and 25 MHz bandwidth, on a 3 V to 20 V single supply or ±3 V to ±10 V dual supplies, ±10 pA typical leakage and a −55 to +125 °C rating. Selection advice: the PWR code is the TSSOP-16 tape-and-reel variant for modern SMT assembly — the same CD4052B function also ships under PDIP and SOIC order codes, so match the package letters to your footprint; the wide supply range is why this 4000-series part still anchors audio routing, sensor selection and test fixtures designed before low-voltage multiplexers existed. TI lists this code as ACTIVE. Parameters verified against Texas Instruments documentation.
