■ELECTRICAL CHARACTERISTICS

(Unless otherwise specified, V+=5V, V-=0V, RL=OPEN, Ta=25℃)

(1) VO= 1.4V, RS=0Ω, 5V < V+< 30V, 0 < VICM<( V+- 1.5V.)

(2) The direction of the input current is out of the IC due to the PNP input stage.

(3) Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the

comparator will provide a proper output state. The low input voltage must not be less than -0.3V (or 0.3V below the negative power supply, if used).

(4) The response time specified is for a 100mV input step with 5mV overdrive.
