Functional Description
The 74VCX16839 consists of twenty selectable non-invert-
ing buffers or registers with word wide controls. Mode func-
tionality 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 20-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
n
to the O
n
outputs. All outputs can be 3-stated by
holding the OE pin at a logic “1.”
