Truth Table (Note 4)
Note 4: A-to-B data flow is shown: B-to-A flow is similar but uses OEBA,
LEBA, and CLKBA.
Note 5: Output level before the indicated steady-state input conditions
were established.
Note 6: Output level before the indicated steady-state input conditions
were established, provided that CLKAB was LOW before LEAB went LOW.
Functional Description
For A-to-B data flow, the LCX16500 operates in the trans-
parent mode when LEAB is HIGH. When LEAB is LOW,
the A data is latched if CLKAB is held at a HIGH or LOW
logic level. If LEAB is LOW, the A bus data is stored in the
latch/flip-flop on the HIGH-to-LOW transition of CLKAB.
Output-enable OEAB is active-HIGH. When OEAB is
HIGH, the outputs are active. When OEAB is LOW, the out-
puts are in the high impedance state.
Data flow for B to A is similar to that of A to B but uses
OEBA, LEBA, and CLKBA. The output enables are com-
plementary (OEAB is active HIGH and OEBA is active
LOW).
