description

The SN75468 and SN75469 are monolithic high-voltage, high-current 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.

The SN75468 has a 2700-Ω series base resistor for each Darlington pair for operation directly with TTL or 5-V
CMOS. The SN75469 has a 10.5-kΩ series base resistor to allow its operation directly with CMOS or PMOS
that use supply voltages of 6 to 15 V. The required input current is below that of the SN75468.
