Functional Description
The 74VCX16838 consists of sixteen selectable non-
inverting buffers or registers with word wide controls. Mode
functionality is selected through operation of the CP and
REGE pin as shown by the truth table. When REGE is held
at a logic
1
the device operates as a 16-bit register. Data
is transferred from I
n
to O
n
on the rising edge of the CP pin.
When the REGE pin is held at a logic
0
the device oper-
ates in a flow through mode and data propagates directly
from the I to the O outputs. All outputs can be 3-STATE by
holding the OE pin at a logic
1.
