(LM2901S) Tlow = −40°C, Thigh = +105°C
6. At the output switch point, VO ] 1.4 Vdc, RS ≤ 100 W 5.0 Vdc ≤ VCC ≤ 30 Vdc, with the inputs over the full common mode range
(0 Vdc to VCC −1.5 Vdc).
7. The bias current flows out of the inputs due to the PNP input stage. This current is virtually constant, independent of the output state.
