Advance Information
CMOS
The MC144112 contains four independent DACs which are controlled
through a common serial data port. When all DACs are utilized, there are 24 bits
in the serial data stream. However, if not all DACs are utilized, the bit stream
length may be reduced by up to six bits per unused DAC.
For new designs, the MC144112 is preferred over the MC144110 and
MC144111. The newer MC144112 offers a wider operating temperature range,
lower operating supply voltage, and lower supply current.
Operating Supply Voltage Range: 2.7 to 5.5 V

Maximum Supply Current (per Package) —
