PECL and ECL are identical circuits.
ECL has the most positive pin as ground and is ideally terminated by 50 ohms to - 2.00 V
PECL has the most negative pin as ground and is ideally terminated by 50 ohms to the most (positive voltage less 2.00 V)
Output Enable Time 200 nS maximum at output enable or 1 mS maximum at output enabled and stable
High Level Input Current
Low Level Input Current -20 uA maximum at Enable / Disable Pin = 0.7 Vcc
-200 uA maximum at Enable / Disable Pin = 0 V
200 nS maximum at output disable
Output Disable Time
Vcc Supply Current disabled < 1 mA. Both outputs are high impedance when disabled.
