MC14549B Description
MC14549B, MC14559B Successive Approximation Registers The MC14549B and MC14559B successive approximation 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.
