The supply pin for the output stage is independent of the supply
pin for the input pin. This allows output levels of different logic
families.
Logic ‘1’ sets the part on hold. Logic levels are RSPECL (Reduced
Swing PECL) compatible.
Logic ‘0’ sets the part on hold. Logic levels are RSPECL
compatible.
The supply pin for the negative supply is connected to the VEEB
via a string of two anti-parallel diodes (see Figure 1)
The supply pin for the input stage is independent of the supply for
the output stage.
The hysteresis voltage is determined by connecting a resistor from
this pin to RHREFA.
Input for analog voltages between 200 mV below VEEA and 2V
below VCCIA.
Input for analog voltages between 200 mV below VEEA and 2V

‘1’ sets the part on hold. Logic levels are RSPECL compatible.
The supply pin for the output stage is independent of the supply
pin for the input pin. This allows output levels of different logic
families.
Output levels are determined by the choice of VCCOB.
