Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may affect device  
reliability and lifetime.  
Note 5: Rise time is measured from 10% to 90% on a ꢀ00mV output signal  
while operating on 1ꢀV supplies with R = 1k, R = 110Ω and R = 100Ω.  
This condition is not the fastest possible, however, it does guarantee the  
internal capacitances are correct and it makes automatic testing practical.

Note 2: A heat sink may be required depending on the power supply voltage.  
Note 6: AC parameters are 100% tested on the ceramic and plastic DIP  
packaged parts (J and N suffix) and are sample tested on every lot of the SO  
packaged parts (S suffix).  
Note 3: This is the total capacitance at Pin 1. It includes the input capacitance  
of the current feedback amplifier and the output capacitance of the  
transconductance amplifier.  
Note 7: NTSC composite video with an output level of 2V.  
Note 4: Slew rate is measured at ꢀV on a 10V output signal while operating  
Note 8: Back to back 6V Zener diodes are connected between Pins 2 and 3  
for ESD protection.
