  • 1.5V to 5.5V operation and balanced noise immunity at 30% of the supply voltage
  • Speed of bipolar F, AS, and S, with significantly reduced power consumption
  • Greater noise immunity than standard inverters
  • Operates with much slower than standard input rise and fall slew rates
  • Balanced propagation delays
  • ±24mA output drive current − fanout to 15F devices
  • SCR latchup-resistant CMOS process and circuit design
