At an appropriate duty cycle depending on ambient temperature and number of drivers turned ON simultaneously, typical power loads totaling over 120 W (350 mA x 7, 50 V) can be controlled. Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters. All devices feature open-collector outputs with integral clamp diodes. The LR2002A/L have series input resistors selected for operation directly with 14-25V PMOS. These devices will handle numerous interface needs - particularly those beyond the capabilities of standard logic buffers. The LR2002A/L are the standard Darlington Array. The outputs are capable of sinking 500 mA and will withstand at least 50V in the OFF state.Outputs may be paralleled for higher load current capability. These Darlington arrays are furnished in 16-pin dual in-line plastic packages (suffix “A”) and 16-lead surface-mountable SOICs (suffix “L”). All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. All devices are rated for operation over the temperature range of -40°C to +85°C. 1/8 ALLOWABLE PACKAGE POWER DISSIPATION IN WATTS LESHAN RADIO COMPANY, LTD.
