S supply voltage for input 1 and LOS1 circuits

I differential circuit 1 input; complimentary to pin IN1Q; DC bias

level is set internally at approximately VCC − 0.33 V

I differential circuit 1 input; complimentary to pin IN1; DC bias level

is set internally at approximately VCC − 0.33 V

S supply voltage for input 1 and LOS1 circuits

− not connected

− not connected

S supply voltage for input 2 and LOS2 circuits

I differential circuit 2 input; complimentary to pin IN2Q; DC bias

level is set internally at approximately VCC − 0.33 V

I differential circuit 2 input; complimentary to pin IN2; DC bias level

is set internally at approximately VCC − 0.33 V

S supply voltage for input 2 and LOS2 circuits

S ground for input 2 and LOS2 circuits

I input for level detector programming of input 1 circuit; threshold

level is set by connecting external resistors between pins VCC1A

and Vref; when forced to GND1A or not connected, the

LOS1 circuit will be switched off

I input for level detector programming of input 2 circuit; threshold

level is set by connecting external resistors between pins VCC2A

and Vref; when forced to GND2A or not connected, the

LOS2 circuit will be switched off

− not connected

I input for programming output level of output 1 circuit; output level

is set by connecting external resistors between

pins VCC1A and Vref; when forced to VCC1A or not connected,

pins OUT1 and OUT1Q will be switched off

I input for programming output level of output 2 circuit; output level

is set by connecting external resistors between pins VCC2A

and Vref; when forced to VCC2A or not connected, pins OUT2

and OUT2Q will be switched off

O reference voltage for level circuit and LOS threshold programming;

typical value is VCC − 1.6 V; no external capacitor allowed

− not connected

I for test purposes only; to be left open-circuit in the application

S ground for output 2 circuit

S supply voltage for output 2 circuit

O PECL or CML compatible differential circuit 2 output;

complimentary to pin OUT2
