Description

General part information

SN74ALVCH162721 Series

This 20-bit flip-flop is designed for low-voltage 1.65-V to 3.6-V VCCoperation.

The 20 flip-flops of the SN74ALVCH162721 are edge-triggered D-type flip-flops with qualified clock storage. On the positive transition of the clock (CLK) input, the device provides true data at the Q outputs if the clock-enable (CLKEN)\ input is low. If CLKEN\ is high, no data is stored.

A buffered output-enable (OE)\ input places the 20 outputs in either a normal logic state (high or low level) or the 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 capability to drive bus lines without 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.
