The 100mA source/sink output is designed to drive power FETs  
directly. The associated output logic is designed to prevent double  
pulsing or cross-conduction current spiking on the output.

The NE5562 is supplied in 20-pin glass/ceramic (Cerdip), plastic  
DIP, and plastic SO packages. The NE grade part is characterized  
and guaranteed over the commercial ambient temperature range of  
0°C to +70°C and junction temperature range of 0°C to +85°C. The  
SE5562 is supplied in the glass/ceramic (Cerdip) package. The SE  
grade part is characterized and guaranteed over the ambient  
temperature range of -55 to +125°C and junction temperature range  
of -55 to +135°C.
