Texas Instruments presents the CD4051B, CD4052B, and CD4053B series, a family of CMOS single 8-Channel, differential 4-Channel, and triple 2-Channel analog multiplexers or demultiplexers with logic-level conversion. Engineered for precise, reliable control of analog and digital signals, these components are characterized by their wide range of signal handling (3 V to 20 V for digital and up to 20 VP-P for analog signals), low ON resistance (125 Ω typical over 15 VP-P signal input range for VDD - VEE = 18 V), high OFF resistance (+100 pA typical channel leakage at VDD - VEE = 18 V), and minimal quiescent power dissipation (0.2 μW typical at VDD - Vss = VDD - VEE = 10 V). They come equipped with on-chip binary address decoding for easy integration and minimized system logic complexity. Available in a variety of package types, including CDIP, PDIP, SOIC, SOP, and TSSOP, these multiplexers/demultiplexers support a broad spectrum of analog to digital and digital to analog conversion applications, signal gating, factory automation, and other uses where reliable signal handling is crucial. With parametric ratings at 5 V, 10 V, and 15 V, and an operational temperature range of -55°C to 125°C, these components are also 100% tested for quiescent current at 20 V, assuring dependable performance across diverse environmental conditions.
