Functional Description
The 74ALVC162839 consists of twenty selectable non-
inverting buffers or registers with word wide modes. Mode
functionality is selected through operation of the CLK and
REGE pin as shown by the truth table. When REGE is held
at a logic HIGH the device operates as a 20-bit register.
Data is transferred from I
CLK input. When the REGE pin is held at a logic LOW the
device operates in a flow through mode and data propa-
gates directly from the I
be 3-stated by holding the OE pin at a logic HIGH.
