MC100EP142中文资料ECL 9 位移位寄存器数据手册ONSEMI规格书

描述 Description

The MC10EP/100EP142 is a 9-bit shift register, designed with byte-parity applications in mind. The E142 performs serial/parallel in andserial/parallel out, shifting in one direction. The nine inputs D0 - D8 accept parallel input data, while S-IN accepts serial input data. The Qn outputs do not need to be terminated for the shift operation to function. To minimize noise and power, any Q output not used should be left unterminated.The SEL (Select) input pin is used to switch between the two modes of operation - SHIFT and LOAD. The shift direction is from bit 0 to bit 8. Input data is accepted by the registers a set-up time before the positive going edge of CLK0 or CLK1; shifting is also accomplished on the positive clock edge. A HIGH on the Master Reset pin (MR) asynchronously resets all the resisters to zero.The 100 Series contains temperature compensation.

简介

MC100EP142属于集成电路（IC）的移位寄存器。由制造生产的MC100EP142移位寄存器移位寄存器是低级逻辑器件，通常用于在串行和并行方式之间转换数字逻辑信号形式的数据，或在数字字内移动数据位的位置。移位寄存器通常使用集成到一个设备中的一组触发器来实现，常用于集成度更高的逻辑器件，但仍可用于 I/O 扩展等应用，在这些应用中离散形式的函数可能会非常有用。
