MM54C905 MM74C905 12-Bit Successive Approximation
Register
General Description
The MM54C905 MM74C905
CMOS 12-bit successive approximation register contains all the digit control and storage necessary for successive approximation analog-to-digital conversion Because of the unique capability of
CMOS to switch to each supply rail without any offset
voltage it can also be used in digital systems as the control and storage element in repetitive routines
