HD74HC354 8-to-1-line Data Selectors/Multiplexer Register (with 3-state outputs) Description This data selectors/multiplexers contains full on-chip binary decoding to select one of eight data sources. The data select address is stored in transparent latches that are enabled by a low level address on pin 11, Select Control. Data on the 8 input lines is stored in a parallel input/output register which in the HD74HC354 is composed of 8 transparent latches enabled by a low level on pin 9, Data Control. Both true (Y) and complementary (W) 3-state outputs are available.
