16-Bit D-Type Flip-Flop
with 3-State Outputs
Product Features
Product Description
• The PI74VCX Family is designed for low voltage
ThePI74VCX16374isparticularlysuitableforimplementing buffer
registers,I/Oports,bidirectionalbusdrivers,andworkingregisters.
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 date
(D) inputs.
operation, V
= 1.8V to 3.6V
DD
• 3.6V I/O Tolerant Inputs and Outputs
• Supports Live Insertion
• Balanced Drive, ±24mA
• Uses patented Noise Reduction Circuitry
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)orahigh-impedancestateinwhichtheoutputsneitherload
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.

• Power-Off high impedance inputs and outputs
• Industrial operation at –40°C to +85°C
• Packaging(Pb-free&Greenavailable):

To ensure the high-impedance state during power up or power
down, OE should be tied to V
through a pullup resistor; the
DD
minimum value of the resistor is determined by the current-
sinking capability of the driver.
The PI74VCX family is I/O Tolerant, allowing it to operate in
mixed 1.8V/3.6V systems.
