CMOS LSI
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.
• Direct R–2R Network Outputs
• Buffered Emitter–Follower Outputs
• Serial Data Input
• Digital Data Output Facilitates Cascading
• Direct Interface to CMOS µP
• Wide Operating Voltage Range: 4.5 to 15 V
• Wide Operating Temperature Range: 0 to 85°C
• Software Information is Contained in Document M68HC11RM/AD

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
Vin and V
out
be constrained to the range VSS ≤
(Vin or V
out
) ≤VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either V
SS
or VDD).
