Features
Low supply current: 440nA per channel
Wide supply range: 1.8V to 40V
Over-the-rail inputs: common-mode range extends 40V above (V-) independent of (V+)
Fail-safe: high impedance inputs with no supply
Power-on-reset provides a known startup condition
No phase reversal for overdriven inputs
Reverse battery protection up to 40V
Push-pull output option (TLV185x)
Open-drain output option (TLV186x)
Temperature range: -40°C to +125°C
