ULN2803A 8 Channel Darlington Transistor Arrays Driver IC in Pakistan

Description:

The ULN2803A is a high-voltage, high-current Darlington transistor array. The device consists of eight
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 connected in parallel for higher current capability. Applications include relay
drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic
buffers. The ULN2803A has a 2.7-k series base resistor for each Darlington pair for operation directly
with TTL or 5-V CMOS devices

Applications:
Motor driver
Relay driver
Led lights driver
Switching
Driving printer hammers
Industrial Equipment
Printers
Features
Output current (single output) 500 mA (max)
High sustaining voltage output 50 V (min)
Output clamp diodes
Inputs compatible with various types of logic CMOS, TTL.
