MC74HC151D中文资料摩托罗拉数据手册PDF规格书

8-Input Data Selector/Multiplexer High–Performance Silicon–Gate CMOS

The MC74HC151 is identical in pinout to the LS151. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

This device selects one of the eight binary Data Inputs, as determined by the Address Inputs. The Strobe pin must be at a low level for the selected data to appear at the outputs. If Strobe is high, the Y output is forced to a low level and the Y output is forced to a high level.

The HC151 is similar in function to the HC251 which has 3–state outputs.
