IK6486是一LED推動芯片，一共有33個LED推動輸出，并提供LED光量調節功能。IK6486與GM6486兼容，并有三種不同的封裝，分別為DIP-40, PLCC-44 和 MQFP-44。

General Description

The IK6486 is a monolithic MOS integrated circuit produced with high voltage CMOS technology. It is available in a 44 pin PLCC package. A single pin controls the LED display brightness by setting a reference current through a variable resistor connected to VDD or to a seperated supply of 13.2V maximum.

Features:

1. 33 outputs, 15mA sink capability;
2. Current generator outputs;
3. Continuous brightness control;
4. Serial data input-output;
5. External load input;
6. Cascade operation capability;
7. Wide supply voltage range;
8. TTL compatibility;

Application:

1. Microprocessor display;
2. Industrial control indicator;
3. Relay driver;
4. Instrumentation readouts;
