The 74ALVCH16600 is an 18-bit universal transceiver featuring
non-inverting 3-State bus compatible outputs in both send and
receive directions. Data flow in each direction is controlled by output
enable (OEAB and OEBA), latch enable (LEAB and LEBA), and clock
(CPAB and CPBA) inputs. For A-to-B data flow, the device operates
in the transparent mode when LEAB is High. When LEAB is Low, the
A data is latched if CPAB is held at a High or Low logic level. If LEAB
is Low, the A-bus data is stor
