MC14559BCP集成電路（IC）的移位寄存器規(guī)格書PDF中文資料

MC14559BCP屬于集成電路（IC）的移位寄存器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC14559BCP移位寄存器移位寄存器是低級(jí)邏輯器件，通常用于在串行和并行方式之間轉(zhuǎn)換數(shù)字邏輯信號(hào)形式的數(shù)據(jù)，或在數(shù)字字內(nèi)移動(dòng)數(shù)據(jù)位的位置。移位寄存器通常使用集成到一個(gè)設(shè)備中的一組觸發(fā)器來實(shí)現(xiàn)，常用于集成度更高的邏輯器件，但仍可用于 I/O 擴(kuò)展等應(yīng)用，在這些應(yīng)用中離散形式的函數(shù)可能會(huì)非常有用。

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. The Feed Forward (FF) of the MC14559B is used for register shortening where End?of?Conversion (EOC) is required after less than eight cycles. Applications for the MC14549B and MC14559B include analog?to?digital conversion, with serial and parallel outputs.
