SLRS023E – DECEMBER 1976 – REVISED JANUARY 2015 SN7546x Darlington Transistor Arrays
1 Features 3 Description The SN75468 and SN75469 are high-voltage, highcurrent Darlington transistor arrays. Each consists of
seven NPN Darlington pairs that feature high-voltage
outputs with common-cathode clamp diodes for
switching inductive loads. The collector-current rating
of each Darlington pair is 500 mA. The Darlington
pairs may be paralleled for higher current capability.
Applications include relay drivers, hammer drivers,
lamp drivers, display drivers (LED and gas
discharge), line drivers, and logic buffers. 1 500-mA Rated Collector Current (Single Output)
