ITT54181 ....................................... -55°Cto 125°C
ITT74181 ................................................ 0°Cto 70°C
Storage temperature range ........... -65°C to 150°C
recommended operating conditions
Notes: 1. Voltage values are with respect to network
ground terminal. .
2. This is the voltage between two emitters of
a multiple emitter transistor. For this circuit.
this rating applies to each A input conjunction
with inputs S2 or 53. and to each B input
in conjunction with inputs SO or S3.
