8-Input Data Selector/Multiplexer With Data and Address Latches and 3-State Outputs
High–Performance Silicon–Gate CMOS

The MC54/74HC354 is identical in pinout to the LS354. The device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC354 selects one of eight latched binary Data Inputs, as determined by the Address Inputs. The information at the Data Inputs is stored in the transparent 8–bit Data Latch when the Data–Latch Enable pin is held high. The Address information may be stored in the transparent Address Latch, which is enabled by the active–high Address–Enable pin.
The device outputs are placed in high–impedance states when Output Enable 1 is high, Output Enable 2 is high, or Output Enable 3 is low.
The HC354 has a clocked Data Latch that is not transparent.
