description/ordering information

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-k

Ω 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.
