CD4514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

描述 Description

CD4514BMS and CD4515BMS consist of a 4-bit strobed latch and a 4-to-16-line decoder. The latches hold the last input data presented prior to the strobe transition from 1 to 0. Inhibit control allows all outputs to be placed at 0(CD4514BMS) or 1(CD4515BMS) regardless of the state of the data or strobe inputs.

The decode truth table indicates all combinations of data inputs and appropriate selected outputs.

These devices are similar to industry types MC14514 and MC14515.
