The Schmitt trigger action provides different threshold voltages for the positive-going (VT+) and negative-going (VT-) input transitions, creating a hysteresis window that makes the gates highly immune to noise on slowly changing or noisy input signals. At 5V supply, the typical hysteresis is 0.9V (VT+ \u2248 2.9V, VT- \u2248 2.0V). This means the output only changes state when the input crosses the upper threshold (rising) or lower threshold (falling), ignoring noise within the hysteresis band. The device can function as a 2-input NAND gate or as a Schmitt trigger inverter by tying both inputs together. The 3V to 18V supply range makes it compatible with both 5V logic and higher-voltage industrial systems. The E suffix denotes the PDIP-14 plastic through-hole package.","working_principle":"Each gate in the CD4093BE combines a 2-input NAND function with a Schmitt trigger input stage. The NAND logic works the same as a standard 2-input NAND gate: the output is LOW only when both inputs are HIGH. The Schmitt trigger adds hysteresis to each input: the input must rise above VT+ (positive-going threshold) to be recognized as HIGH, and must fall below VT- (negative-going threshold) to be recognized as LOW. Between VT- and VT+, the output maintains its previous state. This hysteresis eliminates output oscillation or multiple transitions that would occur with slowly rising\/falling inputs or noisy signals. For a mechanical switch connected to an input through a pull-up resistor, the contact bounce creates multiple fast transitions that a standard gate would pass through to the output; the Schmitt trigger's hysteresis absorbs these bounces and produces a single clean output transition. When both inputs of a gate are tied together, the gate functions as a Schmitt trigger inverter (NOT gate with hysteresis). Two such gates with an RC feedback network create a simple oscillator: the capacitor charges through the resistor until reaching VT+, then the output goes LOW and the capacitor discharges through the resistor until reaching VT-, and the cycle repeats.","pin_description":"\n

        CD4093 is the CMOS 4000-series quad 2-input nand schmitt trigger operating over the wide 3-18V supply range. The HEF4093 (NXP) and MC144093 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC132 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\/7906","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=7906"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7906\/revisions"}],"predecessor-version":[{"id":8197,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7906\/revisions\/8197"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=7906"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=7906"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=7906"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7906"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
