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.
