74F139: High Speed, Dual 1-of-4 Decoder/Demultiplexer

74F139: High Speed, Dual 1-of-4 Decoder/Demultiplexer
The 74F139 is a high speed, dual 1-of-4 decoder/demultiplexer. This device has two independent decoders, each accepting two binary weighted inputs and providing four mutually exclusive active-Low outputs. Each decoder has an active-Low Enable. When Enable is High, every output is forced High. The Enable can be used as the Data input for a 1-of-4 demultiplexer application.

FEATURES
  • Demultiplexing capability
  • Two independent 1-of-4 decoders
  • Multifunction capability

TDA8783: 10-bit ADC for CCD cameras

TDA8783: 10-bit ADC for CCD cameras The TDA8783 is a 10-bit analog-to-digital interface for CCD cameras. The device includes a correlated double sampling circuit, AGC and a low-power 10-bit. Analog-to-Digital Converter (ADC) together with its reference voltage regulator. The AGC and CDS have a bandwidth circuit controlled by on-chip DACs via a serial interface. A 10-bit DAC controls the ADC input clamp level. An additional 8-bit DAC is provided for additional system controls; its output voltage range is 1.4 V (p-p) which is available at pin OFDOUT.
FEATURES
• Correlated Double Sampling (CDS), AGC, 10-bit ADC and reference regulator included, adjustable bandwidth (CDS and AGC)
• Fully programmable via a 3-wire serial interface
• Sampling frequency up to 40 MHz
• AGC gain from 4.5 to 34.5 dB (in 0.1 dB steps)
• CDS programmable bandwidth from 4 to 120 MHz
• AGC programmable bandwidth from 4 to 54 MHz
• Standby mode available for each block for power saving applications 20 mW (typ.)
• 6 dB fixed gain analog output for analog iris control
• 8-bit and 10-bit DAC included for analog settings
• Low power consumption of only 483 mW (typ.)
• 5 V operation and 2.5 to 5.25 V operation for the digital outputs
• TTL compatible inputs, TTL and CMOS compatible outputs.
APPLICATIONS
• CCD camera systems.
