MOTOROLA SEMICONDUCTOR TECHNICAL DATA Successive Approximation Registers The MC14549B and MC14559B successive approximation registers are 8­bit registers providing all the digital control and storage necessary for successive approximation analog­to­digital 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 End­of­Conversion (EOC) is required after less than eight cycles. Applications for the MC14549B and MC14559B include analog­to­digital conversion, with serial and parallel outputs. · Totally Synchronous Operation · All Outputs Buffered · Single Supply Operation · Serial Output · Retriggerable · Compatible with a Variety of Digital and Analog Systems such as the MC1408 8­Bit D/A Converter · All Control Inputs Positive­Edge Triggered · Supply Voltage Range = 3.0 Vdc to 18 Vdc · Capable of Driving Two Low­Power TTL Loads, One Low­Power Schottky TTL Load or Two HTL Loads Over the Rated Temperature Range · Chip Complexity: 488 FETs or 122 Equivalent Gates MAXIMUM RATINGS* (Voltages referenced to VSS) Rating Symbol VDD Vin Iin PD TA Tstg DC Supply Voltage Value Unit Vdc Vdc mAdc mW MC14549B MC14559B L SUFFIX CERAMIC CASE 620 P SUFFIX PLASTIC CASE 648 DW SUFFIX SOIC CASE 751G ORDERING INFORMATION MC14XXXBCP MC14XXXBCL MC14XXXBDW Plastic Ceramic SOIC TA = ­ 55° to 125°C for all packages.
