The Highway09A contains three independent output channels, each capable of driving an LED with a constant current. The current magnitude is typically set internally (e.g., 18.5mA per channel), eliminating the need for external resistors to set the current limit. The current magnitude is typically set internally (e

The following table summarizes the absolute maximum ratings and electrical characteristics (based on standard manufacturer data, typically rated at $T_a = 25^\circ C$).

or sourced through specialized distributors, it is commonly found in a PDIP16 (Plastic Dual In-line Package)
