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 ISL3241E, ISL3243E. For more information on MSL please see tech brief

PIN NAME
FUNCTION
26
VCC
System power supply input (2.7V to 3.6V).
25
VL
Logic power supply. Sets the VOH of all the logic outputs and the switching point of all logic
inputs. Keep VL greater than 1.6V (1.8V - 10%) and less than or equal to VCC. If VL isn't
connected to the Vcc supply, ensure that the VL supply powers up after the Vcc supply.
27
V+
Internally generated positive transmitter supply (typically +5.5V).
31
V-
Internally generated negative transmitter supply (typically -5.5V).
24
GND
Ground connection. This is also the potential of the thermal pad (PD).
28
C1+
External capacitor (voltage doubler) is connected to this lead.
23
C1-
External capacitor (voltage doubler) is connected to this lead.
29
C2+
External capacitor (voltage inverter) is connected to this lead.
