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 brightns control, the LED display brightns is controlled by setting a reference current through a variable ristor connected between a supply and a single pin.
Featur: Continuous brightns 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; Dial clock, thermometer, counter, voltmeter; Instrumentation readouts
