trel Large Signal Response Time
(Vi=TTL,V
ref = +1.4 V, RL= 5.1kΩto VCC+) 300 ns
Notes : 2. At output switch point, VO≈1.4V, RS=0Ωwith VCC+from 5V to 30V and over the full input common-mode range
(0V to VCC+1.5V).
3. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant,
independent of the state of the output, so no loading charge exists on the reference or input lines.
4. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than
0.3V.
The upper end of the common-mode voltage range is VCC+–1.5V, but either or both inputs can go to +30V without
damage.
5. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns
can be obtained.
6. 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 state must
not be less than –0.3V (or 0.3V below the negative power supply, if used).
