Description
Pericom Semiconductors PI74AVC+ series of logic circuits are
produced using the Companys advanced submicron CMOS
technology, achieving industry leading speed.
The PI74AVC+ 16821is a 20-bit bus interface flip-flop designed for
1.65V to 3.6V V
CC
operation. It can be used as two 10-bit flip-flops
or one 20-bit flip-flop. The 20 flip-flops are edge-triggered D-type
flip-flops. On the positive transition of the clock (CLK) input, the
device provides true data at the Q outputs.
A buffered output-enable (OE) input can be used to place the ten
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
CC
through a pullup resistor; the
minimum value of the resistor is determined by the current sinking
capability of the driver.
