High Level Input Current
-20 uA maximum at Enable / Disable Pin = 0.7 Vcc
Low Level Input Current
-200 uA maximum at Enable / Disable Pin = 0 V
Output Enable Time
200 nS maximum at output enable or 1 mS maximum at output enabled and stable
Output Disable Time
200 nS maximum at output disable
Vcc Supply Current disabled < 1 mA. Both outputs are high impedance when disabled.
All other models Output Enable/Disable (E/D)
Output Enable Time
100 nS maximum
Output Disable Time
100 nS maximum
When Disabled
Q Output = Logic Low, QN Output = Logic High. Both Outputs are active
Note 1:
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)
