1. 10LVE 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.
Outputs are termionated through a 50Ω resistor to –2.0V.
2. The same DC parameter values apply across the full VEE range of –3.0 to –3.8V. Outputs are terminated through a 50Ω
resistor to –2.0V. 100LVE circuits are designed to meet the DC specifications shown in the table where transverse airflow
greater than 500 lfpm is maintained.
3. Absolute maximum rating, beyond which device life may be impaired unless otherwise specificed on an individual data sheet.
4. Parametric values specified at:
10LVE Series: –3.0 to –3.8V
100 LVE Series: –3.0 to –3.8V; PECL Power Supply: +3.0V to +3.8V.
5. Guaranteed HIGH signal for all inputs.
6. Guaranteed LOW signal for all inputs.
7. These values are for VCC = 3.3V. Level Specifications will vary 1:1 with VCC.
8. 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.
9. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of theoutput
signal.
10. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device.
11. 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 E111 as a differential input as low as 50 mV will still produce full ECL levels at the output.
12. VCMR is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay
specification. The VIL level must be such that the peak-to-peak voltage is less than 1.0V and greater than or equal to
VPP(min).
