Negative supply input
Channel A, CV_AX reference driven. Comparator output.
Channel B, CV_BX reference driven. Comparator output.
Comparator output logic low supply. Unbuffered analog input that sets all Q_AX, Q_BX “low” voltage level.
Comparator output logic high supply. Unbuffered analog input that sets all Q_AX, Q_BX “high” voltage level.
Positive supply input.

Channel A comparator reference analog input.
Window comparator input. Common to both channel Ax and channel Bx.
Channel B comparator reference analog input.
Power-down logic input (connect to V_EE if not used for power-down).
No internal connection.
