Description
Pericom Semiconductor’s PI74AVC+16820, a 10-bit flip-flop
designed for 1.65V to 3.6V V
edge-triggered D-type flip- flops. On the positive transition of 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
minimum value is determined by the current sinking capability of
the driver.
