Product Description
Pericom Semiconductor’s PI74ALVTC series of logic circuits are
produced using the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
The PI74ALVTC16721 is a 20-bit flip-flop with 3-state outputs
designed specifically for 1.65V to 3.6V V
DD
operation. The device
is designed with edge-triggered D-type flip-flops with qualified
clock storage. On the positive transition of clock (CLK) input, the
device provides true data at the Q outputs, provided that the clock-
enable (CLKEN) input is LOW. If CLKEN is HIGH, no data is stored.
A buffered output-enable (OE) input can be used to place the
20 outputs in either a normal logic state (HIGH or LOW level) or a
high-impedance state. In the high-impedance state, the outputs
neither load nor drive the bus lines significantly. The high-impedance
state and increased drive provide the capacity to drive bus lines
without the need for interface or pullup components. OE does not
affect the internal operation of the flip-flops. 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 V
DD
through a pullup resistor; the
minimum value of the resistor is determined by the current-sinking
capability of the driver.
The family offers both I/O Tolerant, which allows it to operate in
mixed 1.65/3.6V systems, and "Bus Hold," which retains the data
input’s last state preventing "floating" inputs and eliminating the
need for pullup/down resistors.
