RGBDAC3405S

The RGBDAC3405S combines three video speed digital-to-analog converters, three static RAM arrays organized 32*4, internal temperature compensated reference and all the control lines necessary for a full graphics/color monitor interface. All this is contained in a single monolithic low power COMS/TTL compatible IC. In a typical application, each of three independent red, greenn and blue analog outputs will drive a 75 ohm source and load terminated coax that supplies a high resolution video monitor with a palette of 4096 colors. Any of 32 colors are available at a 40 MHz rate. The device can be directly interfaced to CMOS, HCT, TTL and advanced TTL logic families.

There are some RGBDAC3405S features as follows: (1)low power CMOS circuitry; (2)internal interface, temperature compensated; (3)small size-24-pin "skinny" DIP; (4)single +5 V operation; (5)fully synchronous operation for minimal skew; (6)low power CMOS circuitry; (7)ideal interface for videotex systems.

The following is about the RGBDAC3405S absolute maximum ratings: (1)supply voltage, VD-VSS: 6 Vdc max; (2)suppply current (75 loads): 60 mA max; (3)drive into any digital input (clamped): ±10 mA max; (4)output voltage compliance range (each channel): -0.3 to +2.5 V instantaneous; (5)logic input voltage range "0": VSS-0.3 min Vdc; (6)logic input voltage range "1": VDD+0.3 max Vdc; (7)ambient operating temperature range: 0 to +70; (8)ambient storage temperature range: -55 to +125.
