1. 10LVE111 circuits are designed to meet the DC specifications shown in the table after thermal
equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit board and
transverse airflow greater than 500 lfpm is maintained.
2. 100LVE111 circuits are designed to meet the DC specifications shown in the table where transverse
airflow greater than 500 lfpm is maintained.
3. These values are for VCC = 3.3V. Level Specifications will vary 1:1 with VCC.
4. The differential propagation delay is defined as the delay from the crossing points of the differential input
signals to the crossing point of the differential output signals.
5. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the
50% point of the output signal.
6. The within-device skew is defined as the worst case difference between any two similar delay paths within a
single device.
7. VPP(min) is defined as the minimum input differential voltage which will cause no increase in the
propagation delay. The VPP(min) is AC limited for the LVE111 as a differential input as low as 500 mV
will still produce full ECL levels at the output.
8. CMR range is referenced to the most positive side of the differential input signal. Normal operation is
obtained if the high level falls within the specified range and the peak-to-peak voltage lies between
VPP(min) and 1V. The lower end of the CMR range varies 1:1 with VEE and is equal to VEE + 1.5V.
9. For part ordering description, see HPP Part Ordering Information Data Sheet.
