8-input AND-OR-INVERT in a 14-SOIC footprint
The CD4086BMT is a single-gate AND/OR/INVERT logic device from TI's 4000B series, packing 8 inputs arranged as four 2-input AND-OR pairs into a 14-SOIC package. It outputs a single-ended signal, making it a compact glue-logic block for combinatorial functions in mixed-voltage systems. Supply range spans 3 V to 18 V, covering both 5 V and 12 V logic rails commonly found in industrial control and instrumentation. The wide operating temperature of -55°C to 125°C qualifies it for harsh environments like engine bays or outdoor telecom cabinets.
Output drive and logic thresholds
Symmetric output drive of 6.8 mA source and sink at rated supply gives predictable fan-out to standard CMOS loads. No Schmitt-trigger input means the switching threshold follows the standard 4000B Vih/Vil levels — edge rates on the input signals matter for clean transitions. The single 14-SOIC footprint (3.90 mm width) fits a surface-mount assembly line with standard reflow profiles. Tape & Reel packaging supports automated pick-and-place for volume builds.
