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) Mechanical: See Next Pages D Package J Package Replacement B Package M Package Mar 2004 Pl tronics, Inc.
