Three binary address inputs (A, B, C) select one of eight channels to connect to the common output. An inhibit (INH) input disables all channels when high. The device supports analog signals up to 20Vp-p, with the analog range determined by VDD (positive supply) and VEE (negative supply). When VDD=+5V and VEE=-13.5V, analog signals from -13.5V to +5V can be controlled by 0V to 5V digital inputs, providing logic-level conversion. The 125\u03a9 on-resistance at VDD=15V is matched to within 5\u03a9 between channels, ensuring consistent signal transfer. The break-before-make switching prevents momentary shorting between channels during switching. The bidirectional signal path allows use as either a multiplexer (8 inputs to 1 output) or demultiplexer (1 input to 8 outputs). The M96 suffix denotes the SOIC-16 package with tape-and-reel packaging.","working_principle":"The CD4051BM96 uses internally decoded CMOS transmission gates to connect the selected channel to the common terminal. Each channel consists of a parallel n-channel and p-channel MOSFET pair (transmission gate) that provides bidirectional conduction when both MOSFETs are turned on. The 3-bit binary address (A, B, C) is decoded by internal logic to select one of eight channels; when the selected channel's transmission gate is enabled, the n-channel and p-channel MOSFETs both conduct, creating a low-impedance path (125\u03a9 typical at 15V) between the channel I\/O and the common terminal. The parallel n\/p structure ensures a relatively flat on-resistance over the full analog signal range. When the INH pin is high, all transmission gates are disabled, and all channels present high impedance. The break-before-make circuit ensures that the previously selected channel turns off before the newly selected channel turns on, preventing momentary crosstalk between channels. The logic-level conversion works because the digital inputs are referenced to VDD-VSS while the analog switches operate between VDD-VEE; the internal level-shifting circuitry translates the digital control signals to the appropriate gate drive voltages for the transmission gates.","pin_description":"\n

        CD4051 is the CMOS 4000-series 8-channel analog multiplexer\/demultiplexer operating over the wide 3-18V supply range. The HEF4051 (NXP) and MC144051 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC4051 HC\/HCT families offer significantly faster propagation delay and lower power consumption at 2-6V. Surface-mount versions use the BM\/M suffix (SOIC); through-hole versions use the BE suffix (DIP).<\/p>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7880","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=7880"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7880\/revisions"}],"predecessor-version":[{"id":8209,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7880\/revisions\/8209"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=7880"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=7880"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=7880"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7880"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
