1 CHANNEL 8-BIT D/A CONVERTER
The Fujitsu MB4072 is a High-Speed Digital to Analog Converter IC. The
MB4072's current outputs are high impedance open-collector, which provide
voltage output with a load or current to voltage converter for various applications
with operational amplifiers, microcomputers, etc.
Threshold level of digital inputs is variable with the level control input for various
interface level.

PIN ASSIGNMENT
This device contains circuitry to protect the inputs against
damage due to high static voltages or electric fields. However,
it is advised that normal precautions be taken to avoid
application of any voltage higher than maximum rated voltages
to this high impedance circuit.
