16-Bit D-Type Flip-Flop
with 3-STATE Outputs
Product Features
Product Description
• The PI74VCX Family is designed for low voltage
Pericom Semiconductor’s PI74VCX series of logic circuits are
produced in the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
operation, V
= 1.8V to 3.6V
DD
• 3.6V I/O Tolerant Inputs and Outputs
• Supports Live Insertion
The PI74VCX16374 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 date (D) inputs.
• Balanced Drive, ±24mA
• Uses patented Noise Reduction Circuitry
• Typical V

• Typical V
(Output V Undershoot)
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
• Packages available:
48-pin240mil.wideplasticTSSOP(A)
48-pin300mil.wideplasticSSOP(V)
To ensure the high-impedance state during power up or power
down, OE should be tied to V through a pullup resistor; the
minimum value of the resistor is determined by the current-
sinking capability of the driver.
