1 General description
The 74ALVCH16952 consists of two sections, each containing a dual octal non-inverting
registered transceiver. Two 8-bit back to back registers store data flowing in both
directions between two bidirectional buses. Data applied to the inputs is entered and
stored on the rising edge of the clock (nCPAB and nCPBA) provided that the clock
enable (nCEAB and nCEBA) is LOW. The data is then present at the output buffers, but
is only accessible when the output enable input (nOEAB and nOEBA) is LOW. Data flow
from A inputs to B outputs is the same as for B inputs to A outputs.
