Truth Table
(Note 2)
Note 2: A-to-B data flow is shown: B-to-A flow is similar but uses OEBA,
LEBA, and CLKBA.
Note 3: Output level before the indicated steady-state input conditions
were established, provided that CLKAB was HIGH before LEAB went LOW.
Note 4: Output level before the indicated steady-state input conditions
were established.
Functional Description
For A-to-B data flow, the LCX16501 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 LOW-to-HIGH transition of CLKAB. When
OEAB is HIGH, the outputs are active. When OEAB is
LOW, the outputs 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).
