Octal, 14-Bit Voltage-Output DAC

with Parallel Interface

_______________________________________________________________________________________

Note 1: Guaranteed by design. Not production tested.

Note 2: All digital inputs (DB_, A_, WR, CS, LDAC, and CLR) at GND or VCC potential.

Note 3: All digital inputs (DB_, A_, WR, CS, LDAC, and CLR) at +0.8V or +2.4V.

Note 4: All digital inputs (DB0 to DB13) transition from GND to VCC with WR = VCC
