Technical content

  • Package: SOT-723 inverter circuit without connecting external input resistors (see equivalent circuit). * The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. * Only the on/off conditions need to be set for operation, making the device design easy. ◆ Mechanical Characteristics * Lead finish:100% matte Sn(Tin) * Mounting position: Any * Qualified max reflow temperature:260 ℃ ◆ Maximum Ratings (Ta=25℃ unless otherwise specified) Symbol Unit VCC V VIN V IO mA PD mW Tj °C Tstg °C ◆ Electrical Characteristics (Ta=25℃ unless otherwise specified) Test conditions Min.
