6.5 Electrical Characteristics

Over the operating temperature range of TJ = –40°C to 125°C, and 1.8 V < VDD < 18 V, unless otherwise noted.
Typical values are at TJ = 25°C and VDD = 5 V.

(1) The lowest supply voltage (VDD) at which output is active; tr(VDD) > 15 µs/V. Below V(POR), the output cannot be determined.
(2) During power on, VDD must exceed 1.8 V for 450 µs (max) before the output is in a correct state.
(3) High-to-low and low-to-high refers to the transition at the input terminals (INA+ and INB–).
(4) When VDD falls below UVLO, OUTA is driven low and OUTB goes to high impedance. The outputs cannot be determined below V(POR).
