MC14514B集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

MC14514B属于集成电路（IC）的信号开关多路复用器解码器。由安森美半导体公司制造生产的MC14514B信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。

The MC14514B and MC14515B are two output options of a 4 to 16 line decoder with latched inputs. The MC14514B (output active high option) presents a logical “1” at the selected output, whereas the MC14515B (output active low option) presents a logical “0” at the selected output. The latches are R−S type flip−flops which hold the last input data presented prior to the strobe transition from “1” to “0”.

These high and low options of a 4−bit latch / 4 to 16 line decoder are constructed with N−channel and P−channel enhancement mode devices in a single monolithic structure. The latches are R−S type flip−flops and data is admitted upon a signal incident at the strobe input, decoded, and presented at the output.

These complementary circuits find primary use in decoding applications where low power dissipation and/or high noise immunity is desired.
