_---------.----.- General Description
The MX7545 is a 12- bit CMOS multiplying digital- -to-
analog converter (DAC) with internal data latches.
Input data is loaded as a-single 12;bit word and
latched under the control of CS and WR inputs. When
CS and WR are low, the input data latches are trans-

parent and the DAC output responds to any changes
in the digital input.
MX7545 works with a single+5V or +15V power supply.
Electrical characteristics are specified at both of these
supply voltages. With a +5V supply, the digital inputs
are +5V TTL and CMOS compatible while high voltage
CMOS compatibility is maintained at +15V supply
Ordering Information
