8-Line to 1-Line Data Selectors/Multiplexers/Registers
These monolithic data selectors/multiplexers contain 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 on pin 11, SC. On the ‘LS354 and ‘LS355 a similar enable for data is obtained by a low level on
pin 9, DC. The edge-triggered data registers of the ‘LS356 is clocked by a low-to-high transition on
pin 9, CLK. Complementary outputs are available in either three-state versions (‘LS354 and ‘LS356)
or open-collector version (‘LS355).
