Description

   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.

   MC74HC151 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 3state outputs.
