NOTES
1_{Propagation Delay is measured from the input threshold crossing at the 50% point of a 0 V to 5 V input to the output Q and Q crossing.}
2_{Propagation Delay is measured from the input crossing of IE and IE to when the input bias currents drop to 10% of their nominal value.}
3_{Propagation Delay is measured from the input crossing of IE and IE to when the input bias currents rise to 90% of their nominal value.}
4_{Dispersion is measured with input slew rates of 0.5 V/ns and 2.5 V/ns for 5 V swings, 0.5 V/ns and 1 V/ns for 1 V swings.}
5_{The comparator input voltage range is specified for –2 V to +7 V for typical power supply values of -5.2 V and +10.0 V but can be offset for different input ranges such as –1 V to}
+8 V with power supplies of –4.2 V and +11 V, as long as the required headroom of 3 V is maintained between both V_H and +V_S and V_L and +V_S.
Specifications subject to change without notice.
