Each of the two elements can sink 300 mA continuously when the output is low. With open-collector outputs, the load connects between the output pin and a positive supply rail; the driver pulls the output low to energize the load. The 300 mA rating covers most small relays and indicator lamps, but derating is needed if both channels run near the limit simultaneously — the package thermal limit at 70°C ambient will reduce the per-channel capability.
Supply rail and logic interface
The inputs are TTL-compatible, so 3.3 V logic will not reliably drive the inputs to the required high threshold. If your design uses a 3.3 V microcontroller, a level shifter or a different peripheral driver with lower input thresholds is needed.
Package and assembly
The shipping options are Tape & Reel or Cut Tape, which suits both prototyping and volume pick-and-place.
For production BOMs, this part presents no LTB risk.
