HTC KOREA ULN2803A 8-Digit Darlington Current Driver
| Previous | 2 / 4 | Next |
FEATURES
- 8 Darlington Arrays per Package
- 500 mA Rated Collector Current (Single Output)
- Output voltage 50V
- Output Clamp Diodes
- Input Compatible with Various Types of Logic
- Relay-Driver Applications
- Input pins placed opposite to output pins to simplify layout
DESCRIPTION
The ULN2803A is monolithic high-voltage, high-current Darlington transistor arrays. Each 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 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.
