IDT74ALVCH162820

This 10-bit flip-flop is built using advanced dual metal CMOS technology. The ALVCH162820 is an edge-triggered D-type flip-flop. 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 logic 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 capability to drive bus lines without the need for interface or pullup components. OE input 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.

The ALVCH162820 has series resistors in the device output structure which will significantly reduce line noise when used with light loads. This driver has been designed to drive ±12mA at the designated threshold levels. The ALVCH162820 has "bus-hold" which retains the inputs' last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors.
