NOTES:

1. Parametric values specified at:

5 volt Power Supply Range

100E111AE Series:

-4.2V to -5.5V.

10E111AE Series

-4.75V to -5.5V.

3 volt Power Supply Range

10/100E111LE Series: -3.0V to -3.8V.

2. 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.

3. 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.

4. Enable is defined as the propagation delay from the 50% point of a negative transition on EN to the 50% point of a positive transition on Q (or a

negative transition on Q). Disable is defined as the propagation delay from the 50% point of a positive transition on EN to the 50% point of a

negative transition on Q (or a positive transition on Q).

5. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device.

6. The set-up time is the minimum time that EN must be asserted prior to the next transition of IN/IN to prevent an output response greater than

±75mV to that IN/IN transition (see Figure 1).

7. The hold time is the minimum time that EN must remain asserted after a negative going IN or a positive going IN to prevent an output response

greater than

±75mV to that IN/IN transition (see Figure 2).

8. The release time is the minimum time that EN must be de-asserted prior to the next IN/IN transition to ensure an output response that meets the

specified IN to Q propagation delay and output transition times (see Figure 3).

for the E111AE/LE, as a differential input as low as 50mV will still produce full ECL levels at the output.
