ULN2003:输出电压50V，用于低电平逻辑电路和复杂的外围功率负载间的接口的高压，大电流达林顿阵列
Ideally suited for interfacing between low-level logic circuitry and
multiple peripheral power loads, the Series ULN20xxA/L high-voltage,
high-current Darlington arrays feature continuous load current ratings
o 500 mA for each of the seven drivers. At an appropriate duty cycle
depending on ambient temperature and number of drivers turned ON
imultaneously, typical power loads totaling over 230 W (350 mA x 7,
95 V) can be controlled. Typical loads include relays, solenoids,
tepping motors, magnetic print hammers, multiplexed LED and
ncandescent displays, and heaters. All devices feature open-collector
outputs with integral clamp diodes.
