It operates from a 3V to 18V supply, making it compatible with TTL, CMOS, and mixed-voltage logic families without level shifters. Rated for -55°C to 125°C, this part suits avionics, downhole instrumentation, and outdoor telecom equipment where the temperature envelope is wide. ## Supply voltage and temperature grade drive BOM fit The 3V to 18V supply range means the switch can be powered from a single 5V rail or a ±9V dual supply, covering most analog signal swing requirements. The -55°C to 125°C temperature grade is the full military range — the switch's on-resistance and leakage shift with temperature, but the datasheet curves let you budget the worst-case insertion loss and crosstalk.","metaTitle":"MC14066BDR2G onsemi Bilateral FET Switch – 14-SOIC, Active","metaDescription":"onsemi MC14066BDR2G quad bilateral FET switch, 3V-18V supply, -55°C to 125°C, 14-SOIC.
