Functional Description
The LCX841 consists of ten D-type latches with 3-STATE
outputs. The flip-flops appear transparent to the data when
Latch Enable (LE) is HIGH. This allows asynchronous
operation, as the output transition follows the data in transi-
tion.

Latched
On the LE HIGH-to-LOW transition, the data that meets the
setup and hold time is latched. Data appears on the bus
when the Output Enable (OE) is LOW. When OE is HIGH
the bus output is in the high impedance state.
