7. (LM239) Tlow = −25°C, Thigh = +85°
(LM339) Tlow = 0°C, Thigh = +70°C
(MC3302) Tlow = −40°C, Thigh = +85°C
(LM2901) Tlow = −40°C, Thigh = +105°
(LM2901V & NCV2901) Tlow = −40°C, Thigh = +125°C
NCV2901 is qualified for automotive use.
8. 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).
9. The bias current flows out of the inputs due to the PNP input stage. This current is virtually constant, independent of the output state.
10.The response time specified is for a 100 mV input step with 5.0 mV overdrive. For larger signals, 300 ns is typical.
