MM5480数据手册TI中文资料规格书

描述 Description

General Description
The MM5480 is a monolithic MOS integrated circuit utilizing N-channel metal gate low threshold, enhancement mode and ion-implanted depletion mode devices. It utilizes the MM5451 die packaged in a 28-pin package making it ideal for a 3(/2 digit display. The MM5480 is designed to drive common anode-separate cathode LED displays. A single pin controls the LED display brightness by setting a reference current through a variable resistor connected either to VDD or to a separate supply of 11V maximum.
