Seven Darlington pairs in one DIP — what this actually does
The SN75468N is a 7-channel NPN Darlington transistor array in a 16-pin DIP. Each channel can sink up to 500mA continuous collector current with a maximum collector-emitter breakdown of 100V.
100V and 500mA — where the ratings matter
The 100V Vce breakdown covers 24V industrial solenoid banks, 48V telecom relays, and 12V automotive loads with generous headroom. The 500mA per-channel limit is enough for most medium-power relays, small DC motors, indicator lamps, and LED strips.
Automotive grade — AEC-Q100
This part carries AEC-Q100 qualification, meaning it has passed the stress tests for automotive-grade ICs: extended temperature range, high-temperature operating life, and ESD robustness. The operating junction temperature is rated to 150°C, which suits under-hood environments, engine bay electronics, and transmission control modules. For industrial designs that don't need automotive qualification, the AEC-Q100 rating still gives you extra margin on reliability — the part is built to a tighter wafer fab and assembly line than a standard commercial Darlington array.
