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.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-
020.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL55141, ISL55142, ISL55143. For more information on MSL
please see techbrief TB363.
