MX82C171

The MX82C171 is a kind of video DAC which is an integration of three 6-bit digital to analog converter and a color look up table. The DAC section can handle loads of 37.5 or 75 ohms. The microprocessor interface is bidirectional for this 28 pin integrated circuit. It can display 256 colors from a piece of 256K. Full CMOS design reduces power consumption.

There are some features of MX82C171 as follows: (1)pixel rates up to 35 MHz; (2)256 colors; (3)single monolithic, high performance CMOS design; (4)up to 8 bits per pixel; (5)pixel word mask; (6)RGB analog output, 6 bit DAC per gun, composite blank; (7)low DAC glitch energy; (8)video signal output into 75 ohms or doubly terminated 75 ohm cable; (9)TTL compatible inputs; (10)single +5 V±10% power supply; (11)low power dissipation, 750 mW max at maximum pixel rate; (12)the contents of the look-up table and all microprocessor interface registers can be read.

Then is about the absolute maximum ratings about MX82C171: (1)voltage on VCC: 7.0 V; (2)voltage on other pin VSS: -1.5 to VCC+0.5 V; (3)temperature under bias: -40 to 85; (4)storage temperature (ambient): -65 to +150; (5)power dissipation: 1 W; (6)reference current: -15 mA; (7)analog output current (per output): 45 mA; (8)DC digital output current: 25 mA.
