The PI74ALVCH162820 is a 10-bit flip-flop designed for 2.3V to 3.3V VCC operation. The PI74ALVCH162820 is designed with edgetriggered 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 highimpedance 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.
