74ALVT16823DL数据手册集成电路（IC）的触发器规格书PDF

描述 Description

18-bit bus-interface D-type flip-flop with reset and enable; 3-state - The 74ALVT16823 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/address paths of buses carrying parity. The 74ALVT16823 has two 9-bit wide buffered registers with clock enable (pin nCE) and master reset (pin 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. It is designed for VCC operation from 2.5 V to 3.0 V with I/O compatibility to 5 V.
