st2225a 35输出信道数字字母led驱动芯片
the st2225a led display driver is a monolithic cmos ic. in order to achieve continuous brightness control, the led display brightness is controlled by setting a reference current through a variable resistor connected between a supply and a single pin.
features: continuous brightness control; serial data input; no load signal required for data latch; wide power supply operation; ttl compatibility; 35 outputs, 20ma capability; small package, ssop48 and bare chip form
applications: industrial control indicator; relay driver; digital clock, thermometer, counter, voltmeter; instrumentation readouts
