Description

Pericom Semiconductor鈥檚 PI74AVC+16820, a 10-bit flip-flop

designed for 1.65V to 3.6V V

CC

operation. It is designed with

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

CC

through a pullup resistor whose

minimum value is determined by the current sinking capability of

the driver.
