NOTES:
1. 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.
2. 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.
3. 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).
4. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device.
5. 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).
6. 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).
7. 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).
8. V
PP
(min.) is defined as the minimum input differential voltage which will cause no increase in the propagation delay. The V
PP
(min.) is AC limited for the
E111, as a differential input as low as 50mV will still produce full ECL levels at the output.
9. V
CMR
is defined as the range within which the V
IH
level may vary, with the device still meeting the propagation delay specification. The V
IL
level must be
such that the peak-to-peak voltage is less than 1.0V and greater than or equal to V
PP
(min.).
