简述:
18-bit bus-interface D-type flip-flop with reset and enable with 30 Ohm termination resistors; 3-state
-
描述:
The 74ALVT162823 18-bit bus interface register is designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider data or address paths of buses carrying parity.
The 74ALVT162823 has two 9-bit wide buffered registers with clock enable (nCE) and master reset (nMR) which are ideal for parity bus interfacing in high microprogrammed systems.
The registers are fully edge-triggered. The state of each D input, one set-up time before the LOW-to-HIGH clock transition is transferred to the corresponding Q output of the flip-flop.
The 74ALVT162823 is designed with 30 Ω series resistance in both the pull-up and pull-down output structures. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus receivers or transmitters.
