MC14549B, MC14559B
Successive Approximation
Registers
registers are 8−bit registers providing all the digital control and storage
necessary for successive approximation analog−to−digital conversion
systems. These parts differ in only one control input. The Master Reset
(MR) on the MC14549B is required in the cascaded mode when more
than 8 bits are desired. The Feed Forward (FF) of the MC14559B is
used for register shortening where End−of−Conversion (EOC) is
required after less than eight cycles.
analog−to−digital conversion, with serial and parallel outputs.
Features
Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
