Product Description
The PI74ALVTC16374 is particularly suitable for implementing
buffer registers, I/O ports, bidirectional bus drivers, and working
registers. This device can be used as two 8-bit flip-flops or one 16-
bit flip-flop. On the positive transition of the clock (CLK) input, the
Q outputs of the flip-flop take on the logic levels set up at the data
(D) inputs.
A buffered Output Enable (OE) input can be used to place the eight
outputs in either a normal logic state (high or low logic levels) or
a high-impedance state in which the outputs neither load nor drive
the bus lines significantly. The high-impedance state and the
increased drive provide the capability to drive bus lines without
need for interface or pullup components. OE does not affect
internal operations of the flip-flop. Old data can be retained or new
data can be entered while the outputs are in the high-impedance
state.
To ensure the high-impedance state during power up or power
down, OE should be tied to VDD through a pullup resistor; whose
minimum value is determined by the current-sinking capability of
the driver.
The family offers both I/O Tolerant, which allows it to operate in
mixed 1.8/3.6V systems, and “Bus Hold,” which retains the data
input’s last state whenever the data input goes to high-imped-
ance, preventing “floating” inputs and eliminating the need for
pullup/down resistors.
