Each multiplexer selects one of four data inputs (1C0-1C3 or 2C0-2C3) based on the select code and routes it to the corresponding output (1Y or 2Y). When the strobe is HIGH, the output is forced LOW regardless of data and select inputs. The shared select inputs make the 74153 ideal for selecting two related signals simultaneously \u2014 for example, selecting the upper and lower nibbles of a data byte from four sources. Two 74153 chips can be combined to form an 8:1 multiplexer: the shared select inputs select one of four sources on each chip; a 3rd select bit (via an inverter) enables one chip while disabling the other; the outputs are ORed. The 74153 can also implement any 3-variable Boolean function by tying the four data inputs to VCC or GND per the truth table. The N suffix denotes the PDIP-16 through-hole package.","working_principle":"Each 4:1 multiplexer in the SN74LS153N selects one of four data inputs based on the 2-bit select code BA: BA=00 selects C0, BA=01 selects C1, BA=10 selects C2, BA=11 selects C3. The selected input appears at the Y output when the strobe G is LOW. When G is HIGH, Y=0 regardless of the data and select inputs. The logic function: Y = G' \u00b7 (C0\u00b7B'\u00b7A' + C1\u00b7B'\u00b7A + C2\u00b7B\u00b7A' + C3\u00b7B\u00b7A). The two multiplexers share the same select inputs (A, B) but have independent data inputs, strobes, and outputs. This shared-select arrangement ensures that both multiplexers switch to the same source number simultaneously \u2014 critical for parallel data routing. For function generation: tie C0-C3 to VCC (1) or GND (0) according to the desired truth table for a 3-variable function (B, A are two variables; the strobe G can be the third). For example, XOR of A and B: C0=0, C1=1, C2=1, C3=0, with G=LOW always.","pin_description":"\n

        The 74153 is a Dual 4-Line to 1-Line Data Selector\/Multiplexer. Family variants span from the original LS TTL (5V only) to modern LVC\/AUP (down to 0.8V). HC and HCT versions offer 2-6V CMOS operation with HCT providing TTL-compatible input thresholds for mixed 5V systems. CD4000-series equivalents offer the widest 3-18V supply range at the cost of lower switching speed. DIP packages (N suffix) are through-hole; SOIC (D suffix) and TSSOP are surface-mount.<\/p>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7979","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=7979"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7979\/revisions"}],"predecessor-version":[{"id":8157,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7979\/revisions\/8157"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=7979"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=7979"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=7979"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=7979"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
