3 Description

The SN75468 and SN75469 are 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.
