TECHNICAL DATA
HIGH-VOLTAGE HIGH-CURRENT
DARLINGTON TRANSISTOR ARRAYS
The
KK2003A
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
KK2003A
has a 2.7-k
series base resistor for each
Darlington pair for operation directly with TTL or 5-V CMOS
devices.
