Introduction
The MC144110 and MC144111 are low-cost 6-bit D/A
converters with serial interface ports to provide
communication with CMOS microprocessors and
microcomputers. The MC144110 contains six static D/A
converters; the MC144111 contains four converters.
Due to a unique feature of these DACs, the user is
permitted easy scaling of the analog outputs of a system.
Over a 5 to 15 V supply range, these DACs may be
directly interfaced to CMOS MPUs operating at 5 V.

Storage Temperature Range
This device contains protection circuitry to guard against damage due to high static voltages or electric
fields; however, it is advised that precautions be taken to avoid application of voltage higher than
maximum rated voltages to this high-impedance circuit. For proper operation it is recommended that V
in
and V
out
be constrained to the range V
SS
≤
(V
in
or V
out
)
≤V
DD
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either V
SS
or V
DD
).
