8CH DARLINGTON SOURCE DRIVER
IK62783/4
IK62783N
IK62784N
The IK62783, IK62784 are eight current drivers with
common power supply and ground.
The IK62783, IK62784 are purposed to use different
devices: relays, lamps, displays (LED & gas discharge
cells), in fluorescent indicators, telecommunication lines
and logic devices.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
