The CBM2003A are monolithic high-voltage, high-current Darlington transistor arrays. Each
consists of seven n-p-n Darlington pairs that feature high-voltage outputs with
common-cathode clamp diodes for switching inductive loads. The collector-current rating of a
single 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.
The CBM2003A has a 2.7-kΩ series base resistor for each Darlington pair for operation
directly with TTL or 5-V CMOS devices.
