Digital-to-Analog Converters with
Serial Interface
CMOS LSI
1
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.
Freescale reserves the right to change the detail specifications as may be required to permit improvements in the design of its
products.
