Introduce this Module:
The ULN2803A device is a 50 Volt, 500 Milliamp Darlington transistor. The device consists of 8 NPN Darlington pairs that feature high-voltage outputs with com-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 Milliamp. The Darlington pairs may be connected in parallel for higher-level current capability.
Some Core Parameters of the Module:
SPECIAL FEATURES :
● 500-mA-Rated Collector Current (Single Output)
● High-Voltage Outputs: 50V
● Output Clamp Diodes
● Input Compatible with Various Types of Logic IC.
● TTL, DTL, CMOS or PMOS Compatible Inputs s Output Current to 500 milliamps
● Transient-Protected Outputs
● Dual In-Line Package.
● Wide-Body Small-Outline Package.
