Description
Pericom Semiconductor’s PI74ALVCH series of logic circuits are
produced in the Company’s advanced 0.5 micron CMOS
technology, achieving industry leading speed.
The PI74ALVCH16821 is a 20-bit bus interface flip-flop designed
for 2.3V to 3.3V V
CC
operation. It can be used as two 10-bit flip-
flops or one 20-bit flip-flops. 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.
Active bus-hold circuitry is provided to hold unused or floating
data inputs at a valid logic level.
