RGBDAC3400S

The RGBDAC3400S combines three video speed digital-to-analog converters, internal temperature compensated reference and all control lines necessary for a full graphics/color monitor interface. All this is contained in a single monolithic low power CMOS/TTL compatible IC. In a typical application, each of three independent red, green 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. The device can be directly interfaced to CMOS, HCT, TTL and advanced TTL logic families. The device includes all three DACs and latches in a single, cost effective dual-in-line package with 24 pins 0.3 inches wide.

There are some RGBDAC3400S features as follows: (1)state of the art single chip monolithic; (2)internal reference, 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 system.

The following is about the RGBDAC3400S absolute maximum ratings: (1)supply voltage, VDD-VSS: 6 Vdc max; (2)supply current (75 loads): 60 mA max; (3)full scale output current: 40 mA max; (4)drive into any digital input (clamped): ±10 mA; (5)output voltage compliance range (each channel): -0.3 to +2.5 V instantaneous; (6)logic input voltage range "0": VSS-0.3 min Vdc; (7)logic input voltage range "1": VDD+0.3 max Vdc; (8)ambient operating temperature range: 0 to 70; (9)ambient storage temperature range; -55 to +125.
