- Up and down level-shifting capability.
- Three-state outputs with separate enable controls.
- Standardized, symmetrical output characteristics.
- 100% tested for quiescent current at 20 V.
- Low input current: 1 μA at 18 V over the full package-temperature range; 100 nA at 18 V and 25°C.
Applications
- High-or-low level-shifting with three-state outputs for unidirectional or bidirectional bussing.
- Isolation of logic subsystems using separate power supplies, addressing supply sequencing, supply loss, and supply regulation considerations.
